{cmd:coefplot} plots results from estimation commands or Stata matrices.
|
|
|
Results from multiple models or matrices can be combined in a single
|
|
|
graph. The default behavior of {cmd:coefplot} is to draw markers for
|
|
|
coefficients and horizontal spikes for confidence intervals. However,
|
|
|
{cmd:coefplot} can also produce various other types of graphs.

{cmd:b(}{it:mspec}{cmd:)} specifies the source from which the point

estimates and coefficient names are to be collected. The default is to use
|
|
|
(the first row of) {cmd:e(b)} (or {cmd:e(b_mi)} if plotting results from
|
|
|
{helpb mi estimate}). {cmd:b()} is discarded in matrix mode (see

{it:mspec} may be:

{p2colset 13 25 27 2}{...}

{marker at}{...}
|

{phang}
|
|
|
{cmd:at}[{cmd:(}{it:spec}{cmd:)}] causes plot positions to be determined
|
|
|
by the values in {cmd:e(at)} (or matrix {cmd:at}) or as specified by
|
|
|
{it:spec}. The default is to create a categorical axis with coefficients
|
|
|
matched by their names. However, if {cmd:at} is specified, the axis is
|
|
|
treated as continuous. Note that labeling options
|
|
|
{cmd:coeflabels()}, {cmd:eqlabels()}, {cmd:headings()}, or {cmd:groups()}
|
|
|
are not allowed if {cmd:at} is specified. Also not allowed with {cmd:at}
|
|
|
are options {cmd:bycoefs}, {cmd:order()}, and {cmd:relocate()}.
|
|
|
Furthermore, note that {cmd:at} has to be specified for all models or
|
|
|
for none. {it:spec} is
|
|
|
|
|
|
[{it:atspec}] [{cmd:,} {opt t:ransform(exp)}]
|
|
|
|
|
|
{pmore}
|
|
|
where {it:atspec} may be
|
|
|
|
|
|
{p2colset 13 27 29 2}{...}
|
|
|
{p2col:{it:mspec}}as above for {helpb coefplot
|
|
|
{p_end}
|
|
|
{p2col:
|
|
|
{p_end}
|
|
|
{p2col:{opt m:atrix(mspec)}}read from matrix instead of {cmd:e()}
|
|
|
{p_end}
|
|
|
{p2col:{opt _coef}}use coefficient names as plot positions
|
|
|
{p_end}
|

{p2col:{opt _eq}}use equation names as plot positions
|
|
|
{p_end}
|
|
|
{p2colreset}{...}
|
|
|
|
|
|
{pmore}
|
|
|
If {cmd:at} is specified without argument, the plot positions are taken from the first row
|
|
|
of {cmd:e(at)} (or matrix {cmd:at}). A special case are results from
|
|
|
{helpb margins} where recovering the plot positions is more
|
|
|
complicated. The default in this case is to use the first
|
|
|
at-dimension. Type, e.g., {cmd:at(2)} if multiple at-dimension were specified
|
|
|
with {helpb margins} and you want to use the second dimension. Furthermore,
|
|
|
in matrix mode (see
|
|
|
{help coefplot
|
|
|
would read the plot positions from the 2nd row (or column) of the main matrix.
|
|
|
|
|
|
{pmore}
|
|
|
When plotting results from {cmd:e()} it is sometimes convenient to
|
|
|
maintain an external matrix with the plot positions instead of
|
|
|
adding plot positions to each {cmd:e()}-set. In this case you can use
|
|
|
syntax {cmd:at(matrix(}{it:mspec}{cmd:))} to read the plot positions. Note
|
|
|
that the vector of plot positions must have the same length as the
|
|
|
coefficient vectors of the plotted models; elements are matched by position,
|
|
|
not by name.
|
|
|
|
|
|
{pmore}
|
|
|
Furthermore, {cmd:at(_coef)} or {cmd:at(_eq)} will use the coefficient names or
|
|
|
the equation names as plot positions, respectively. This is useful only if
|
|
|
the coefficient names or the equation names are numeric. Note that you may
|
|
|
use {helpb coefplot
|
|
|
{helpb coefplot
|
|
|
from coefficient names or equation names.
|
|
|
|
|
|
{pmore}
|
|
|
Suboption {cmd:transform()} transforms the plot positions before creating
|
|
|
the graph. Within the transformation expression, use {cmd:@} as a
|
|
|
placeholder for the value to be transformed. For example, to take the
|
|
|
antilogarithm of the plot positions type {cmd:transform(exp(@))}.
|
|
|
|
|
|
{marker keep}{...}
|
|
|
{phang}
|
|
|
{cmd:keep(}{it:coeflist}{cmd:)} specifies the coefficients to be
|
|
|
plotted. The default is to include all coefficients from the
|
|
|
first (nonzero) equation of a model (and discard further equations).
|
|
|
{it:coeflist} is a space-separated list of
|
|
|
elements such as:
|
|
|
|
|
|
{p2colset 13 25 27 2}{...}
|
|
|
{p2col:{it:coef}}keep coefficient {it:coef}
|

{p2col:{it:eq}{cmd::}}keep all coefficients from equation {it:eq}

quantile of the standard normal distribution or the t-distribution (if degrees

|
of freedom are available; see above), where {it:a} is 1 minus the

confidence level (e.g. {it:a}=5% for a 95% confidence interval). Then the

{cmd:citype(logit)} uses the logit transformation to compute the limits

of confidence intervals. This is useful if the estimates to be plotted are

proportions and the confidence limits are supposed to lie between 0 and
|
|

{cmd:citype(atanh)} uses the inverse hyperbolic tangent to compute the

{cmd:citype(log)} computes log-transformed confidence intervals. This is useful

not all of Stata's plot types support marker labels. For example, if you use

{helpb twoway_bar:bar}, no marker labels will be displayed (this has

The {cmd:mlabel} option can be used in three different ways:
|
|
|
|
|
|
{pmore2}
|
|
|
(1) {opt mlabel} without argument adds the values of the point estimates as
|
|
|
marker labels. Use global option
|
|
|
{helpb coefplot
|
|
|
|
|
|
{pmore2}
|
|
|
(2) {opth mlabel(varname)} uses the values of the specified variable
|
|
|
as marker labels. {it:varname} may be an internal variable (see
|
|
|
{help coefplot
|
|
|
{cmd:mlabel(@b)} is equivalent to {cmd:mlabel} without argument.
|
|
|
|
|
|
{pmore2}
|
|
|
(3) {opt mlabel(strexp)} sets the marker labels to the evaluation of the
|
|
|
specified string expression. Internal variables can be used within {it:strexp}
|
|
|
(see {help coefplot
|
|
|
below). For example, you can type
|
|
|
|
|
|
{pmore3}
|
|
|
mlabel("p = " + string(@pval,"%9.3f"))
|
|
|
|
|
|
{pmore2}
|
|
|
to display labels such as "p = 0.001" or "p = 0.127". Furthermore,
|
|
|
|
|
|
{pmore3}
|
|
|
mlabel(cond(@pval<.001, "***", cond(@pval<.01, "**", cond(@pval<.05, "*", ""))))

{cmd:orderby(}[{it:subgraph}{cmd::}][{it:plot}]{cmd:)} orders the

according to how they are provided to {cmd:coefplot}, with earlier plots

and subgraphs taking precedence over later ones (and placing {cmd:_cons}
|

be placed after the coefficients that appear in earlier models. Specify the

{cmd:orderby()} option if you want to change the default behavior and
|

arrange the coefficients according to their order in a specific model

(and, within each equation, place the other coefficients after these coefficients, but

before {cmd:_cons}). Arguments {it:subgraph} and {it:plot} select the relevant

model. For example, {cmd:orderby(2:3)} will order coefficients according to
|
|
|
the model that is displayed in the third plot of the second subgraph. If one

of the arguments is omitted, it defaults to one. Hence, {cmd:orderby(3)} will

order the coefficients according to the model displayed in the third plot

length of

words. That is, they try to fill to the maximum length without breaking

Note: Labels containing multiple lines are left unchanged by {cmd:truncate()}

Instead of providing distinct model names to {cmd:coefplot}, you can also
|
|
|
specify a name pattern containing {cmd:*} (any string)
|
|
|
and {cmd:?} (any nonzero character) wildcards. {cmd:coefplot}
|
|
|
will then plot the results from all matching
|
|
|
models. If a name pattern is specified as part of a plot delimited by
|
|
|
parentheses, the results from the matching models will be combined into the
|
|
|
same plot. For example, if models {cmd:est11}, {cmd:est12}, {cmd:est13},
|
|
|
{cmd:est21}, {cmd:est22}, and {cmd:est23} are in
|
|
|
memory, typing

|
|
|
{txt}{...}
|
|
|
|

{title:Placement of options}
|

{pstd}
|
|
|
{cmd:coefplot} has four levels of options:
|
|
|
|
|
|
{phang}(1) {help coefplot
|
|
|
model (or matrix). They specify the information to be displayed.
|
|
|
|
|
|
{phang}(2) {help coefplot
|
|
|
plot, possibly containing results from multiple models. They affect
|
|
|
the rendition of markers and confidence intervals and provide a label
|
|
|
for the plot.
|
|
|
|
|
|
{phang}(3) {help coefplot
|
|
|
apply to a single subgraph, possibly containing multiple plots.
|
|
|
|
|
|
{phang}(4) {help coefplot
|
|
|
to the overall graph.
|
|
|
|
|
|
{pstd}
|
|
|
The levels are nested in the sense that upper level options include all
|
|
|
lower level options. That is,
|
|
|
{help coefplot
|
|
|
{help coefplot
|
|
|
{help coefplot
|
|
|
{help coefplot

{help coefplot
|
|
|
{help coefplot
|
|
|
{help coefplot
|
|
|
{help coefplot
|
|
|
may not be specified at a lower level.
|
|
|
|
|
|
{pstd}
|
|
|
If lower level options are specified at an upper level, they serve as
|
|
|
defaults for all included lower levels elements. For example, if you want
|
|
|
to draw 99% and 95% confidence intervals for all included models,
|
|
|
specify {cmd:levels(99 95)} as global option:
|
|
|
|
|
|
{com}{...}
|
|
|
. coefplot model1 model2 model3, levels(99 95)
|
|
|
{txt}{...}
|
|
|
|
|
|
{pstd}
|
|
|
Options specified with an individual element override the defaults set
|
|
|
by upper level options. For example, if you want to draw 99% and 95%
|
|
|
confidence intervals for model 1 and model 2 and 90% confidence intervals
|
|
|
for model 3, you could type:
|
|
|
|
|
|
{com}{...}

There are some fine distinctions about the placement of options and how they
|
|
|
are interpreted. For example, if you type
|
|
|
|
|
|
{com}{...}
|
|
|
. coefplot m1, {txt:{it:opts1}} || m2, {txt:{it:opts2}} {txt:{it:opts3}}
|
|
|
{txt}{...}
|
|
|
|
|
|
{pstd}
|
|
|
then {it:opts2} and {it:opts3} are interpreted as global options. If you
|
|
|
want to apply {it:opts2} only to {cmd:m2} then type
|
|
|
|
|
|
{com}{...}
|
|
|
. coefplot m1, {txt:{it:opts1}} || m2, {txt:{it:opts2}} ||, {txt:{it:opts3}}
|
|
|
{txt}{...}
|
|
|
|
|
|
{pstd}
|
|
|
Similarly, if you type
|
|
|
|
|
|
{com}{...}
|
|
|
. coefplot (m1, {txt:{it:opts1}} \ m2, {txt:{it:opts2}})
|
|
|
{txt}{...}
|
|
|
|
|
|
{pstd}
|
|
|
then {it:opts2} will be applied to both models. To apply {it:opts2} only to
|
|
|
{cmd:m2} type
|
|
|
|
|
|
{com}{...}
|
|
|
. coefplot (m1, {txt:{it:opts1}} \ m2, {txt:{it:opts2}} \)
|
|
|
{txt}{...}
|
|
|
|
|
|
{pstd}
|
|
|
or, if you also want to include {it:opts3} to be applied to both models,
|
|
|
type
|
|
|
|
|
|
{com}{...}
|
|
|
. coefplot (m1, {txt:{it:opts1}} \ m2, {txt:{it:opts2}} \, {txt:{it:opts3}})
|
|
|
{txt}{...}
|
|
|
|
|
|
{pstd}
|
|
|
or
|
|
|
|
|
|
{com}{...}
|
|
|
. coefplot (m1, {txt:{it:opts1}} \ m2, {txt:{it:opts2}} \), {txt:{it:opts3}}
|
|
|
{txt}{...}
|
|
|
|
|
|
{pstd}
|
|
|
In case of multiple subgraphs there is some ambiguity about where to
|
|
|
specify the plot options (unless global option
|
|
|
{helpb coefplot
|
|
|
options within any of the subgraphs as plot options are collected across
|
|
|
subgraphs. However, in case of conflict, the plot options from the rightmost
|
|
|
subgraph usually take precedence over earlier plot options. In addition,
|
|
|
you can also use global options {helpb coefplot
|
|
|
{helpb coefplot
|
|
|
options for specific plots. In case of conflict, options specified within a plot take
|
|
|
precedence over options provided via {helpb coefplot

Use syntax {helpb coefplot

name of a stored model to plot results from a matrix. {it:mspec} may be:
|
|
|
|
|
|
{p2colset 9 21 23 2}{...}

{p2col:{it:name}}use first row of matrix {it:name}
|
|

{p_end}
|

|
{p2col:{it:name}{cmd:[}
|
|

matrix {it:name}; may also type {it:name}{cmd:[}
|
|
|
{it:name}{cmd:[}
|
|
|
{p_end}
|
|
|
{p2col:{it:name}{cmd:[.,}

matrix {it:name}; may also type {it:name}{cmd:[,}

{p_end}
|
|
|
{p2colreset}{...}
|
|
|
|
|
|
{pstd}
|
|

If the {cmd:matrix()} syntax is used, then option {helpb coefplot
|
|
|
and names given in {helpb coefplot
|
|
|
{helpb coefplot
|
|
|
{helpb coefplot
|
|
|
matrices instead of {cmd:e()}-matrices. The matrix name may be omitted in these
|
|
|
options if results are to be read from the same matrix; only the
|
|
|
relevant row or column numbers have to be provided in this case (whether the
|
|
|
numbers are interpreted as row or column numbers
|
|
|
depends in how {cmd:matrix()} was specified).

For example, to plot medians and their confidence intervals as computed
|
|
|
by {helpb centile} you could type:
|
|
|
|
|
|
{com}{...}
|
|
|
sysuse auto, clear
|
|
|
matrix C = J(3,3,.)
|
|
|
matrix rownames C = median ll95 ul95
|
|
|
matrix colnames C = mpg trunk turn
|
|
|
local i 0
|
|
|
foreach v of var mpg trunk turn {
|
|
|
local ++ i
|
|
|
centile `v'
|
|
|
matrix C[1,`i'] = r(c_1) \ r(lb_1) \ r(ub_1)
|
|
|
}
|
|
|
matrix list C
|
|
|
coefplot matrix(C), ci((2 3))
|
|
|
{txt}{...}
|
|
|
|
|
|
{pstd}
|
|
|
This is equivalent to:
|
|
|
|
|
|
{com}{...}
|
|
|
coefplot matrix(C[1]), ci((C[2] C[3]))
|
|
|
{txt}{...}
|
|
|
|
|
|
{pstd}
|
|
|
Note that a single {cmd:coefplot} command can contain both regular syntax
|
|
|
and {cmd:matrix()} syntax. For example, to add means to the graph above
|
|
|
you could type:
|
|
|
|
|
|
{com}{...}
|
|
|
mean mpg trunk turn
|
|
|
estimates store mean
|
|
|
coefplot (matrix(C), ci((2 3))) (mean)

{cmd:coefplot} maintains a number of internal variables that can be

|
{p2colset 9 21 23 2}{...}
|
|

The internal variables can be used like other variables in the
|
|
|
dataset. For example, option {cmd:mlabel(@plot)} would add plot labels as marker
|
|
|
labels or option {cmd:addplot(line @at @b)} would draw a connecting line
|
|
|
through all point estimates in the graph.
