MLT: Stata module to provide multilevel tools

The mlt package contains some postestimation commands for hierarchical mixed models (xtmixed, xtmelogit and xtmepoisson) and some other tools useful for typical tasks in multilevel modelling. mltrsq computes the Bosker/Snijders and Bryk/Raudenbush R-square values for mixed models with two levels after xtmixed. mlt2stage computes two-stage (or slopes as outcomes) results for linear and logistic regression models. mltl2scatter produces bivariate scatter plots for higher-level units. mltcooksd computes influence measures Cook's D and DFBETAs for higher level units in hierarchical mixed models after xtmixed, xtmelogit and xtmepoisson. mltshowm shows models excluding influential cases after mltcooksd.
