correlation(exchangeable) provides for one correlation coefficient common to all latent variables, except the latent variable associated with the basealternative() option. correlation(independent) assumes that all correlations are zero. correlation(pattern matname) and correlation(fixed matname) give you ...
It is not a correlation coefficient, but it shares certain prop- erties with correlation coefficients. It is bounded by −1 and 1, and 0 has the same meaning, namely, no correlation. autoregressive models. Spatially autoregressive models include a spatially lagged dependent variable or spatially...
PROC CORR supplies tetrachoric/polychoric correlation coefficients, standard errors, and two tests of statistical significance (i.e., that the correlation is significantly different from 0). To test goodness of fit (for a single polychoric correlation coefficient only) one can use PROC IRT: proc ...
While you can often just throw items into SPSS to compute a coefficient alpha on a scale measure, there are several additional questions one must ask when computing an ICC, and one restriction. The restriction is straightforward: you must have the same number of ratings for every...

For calculation of confidence intervals around estimates, the intra- and between-cluster correlation has been taken into account using the svy command in Stata. Determinants of survival in serviceable condition after the net was first hung were explored using Cox proportionate hazard models. Factors ...

Stata's mestreg command that was introduced in Stata 14 does just that. Survival models are usually formulated using the proportional-hazards parameterization or using the accelerated failure-time (AFT) parameterization, both of which are available with mestreg. One of the advantages of the AFT ...

I am using the user-contributed command -mixlogit- from the SSC archive with three fixed coefficient terms on dummy variables and four random coefficients. I've read "Fitting mixed logit models using maximum simulated likelihood" in The Stata Journal, 2007, 7 (3), 388 - 401 by Arne Risa ...
