| where {it:b} is a 1 x p coefficient vector | |
| (matrix) and {it:V} is a p x p covariance matrix. | |
| {title:Description} | |
| {p 4 4 2} | |
| {cmd:erepost} changes the {cmd:b} or {cmd:V} matrix of the current estimation results | |
| or changes the declared estimation sample. {cmd:erepost} is similar to | |
| {helpb ereturn repost}. However, {cmd:erepost} is allowed | |
| after estimation commands that do not post their results | |
| using {cmd:ereturn post} (e.g. {cmd:logit}) and {cmd:erepost} | |
| can be used outside of {cmd:eclass} programs (see help {helpb program}). | |
| {p 4 4 2} | |
| Technical note: After applying {cmd:erepost} the original command (or | |
| {cmd:estimates replay}) may not be able to replay the output. | |
| {title:Options} | |
| {p 4 8 2} | |
| {cmd:cmd(}{it:string}{cmd:)} sets the {cmd:e(cmd)} macro. | |
| {p 4 8 2} | |
| {cmd:rename} causes the names from the coefficient vector to be used | |
| as the labels for both the coefficient vector and the covariance matrix | |
| in case of name conflicts. | |
| {p 4 8 2} | |
| {cmd:esample(}{it:varname}{cmd:)} gives the name of the 0/1 variable | |
| indicating the observations involved in the estimation. The variable is | |
| removed from the data but is available for use as {hi:e(sample)}. Specify {cmd:noesample} | |
| if you want to remove {cmd:e(sample)} from the estimation results. | |
| {p 4 8 2} | |
| {it:ereturn_post_opts} are any other options allowed with {cmd:ereturn post} | |
| (see help {helpb ereturn}). | |
| {title:Examples} | |
| {p 4 4 2}Say, you are estimating a regression model that contains all interactions between the | |
| regressors and a binary variable and you want to display the main effects and the | |
| interaction effects in two columns side by side. One approach is to modify the names | |
| in {cmd:e(b)} and {cmd:e(V)} so | |
| that there is a "main equation" and an "interaction equation" and then tabulate | |
| the model using {cmd:estout} or {cmd:esttab} with the {cmd:unstack} option. Example | |
| (you will need the {cmd:estout} package to run this example; type | |
| {net "describe http://fmwww.bc.edu/repec/bocode/e/estout.pkg":ssc describe estout}): | |
