During grad school, I attended an ESA Workshop on Structural Equation Modeling (SEM) let by Jim Grace. The approach allows for multivariate analysis with multiple predictors, multiple response variables, and latent variables. Up until now, my research never re... | |
# Designation of a term in a sequence in Second-order Logic
To First-order Logic, like in Hodges "A Shorter Model Theory", we can designate a $L$-term $t$ in a structure $\mathfrak{A}$ considering a sequence $\bar{a}$ of elements of the domain $A$ of $\mathfrak{A}$, by complexity on the terms:
• if $t$ is a variable ... | |

### how the second line of lyman series is produced
The series of lines in an emission spectrum caused by electrons falling from energy level 2 or higher (n=2 or more) back down to energy level 1 (n=1) is called the Lyman series. How satisfied are you with the answer? (2) The group of lines produced when the electron ... | |
## Appendix ACleaning the raw data
There are two ways to clean time-series data:
(1)
Run makemap and add doclean = 1 to your configuration (see Section 5.4.3).
(2)
Run sc2clean to clean the time-series data without making a map.
The rest of this appendix gives more details on using sc2clean.
sc2clean can be used to... | |
