MODELDIAG: Stata module to generate graphics after regression

modeldiag is a set of graphics programs to run after fitting a regression-type command. Programs are written for Stata 8, except that in most cases a previous version written for Stata 7 is also included here. Numbering conventions are that "2" added to the name indicates a program offered as a generalisation of the corresponding official Stata command and that "7" added to the name indicates a program written for Stata 7.
