Graphics before and after model fitting

It is commonplace to compute various flavours of residual and predicted values after fitting many different kinds of model. Official Stata supplies as built-ins a bundle of commands originally written for use after regress: avplot, avplots, cprplot, acprplot, lvr2plot, rvfplot and rvpplot. These were introduced in Stata 3.0 in 1992 and are documented at [R] regdiag. More recently, in an update to Stata 7.0 on 6 September 2001, all but the first two have been modified so that they may be used after anova. Despite their many uses, this suite omits some very useful kinds of plot, while none of the commands may be used after other modelling commands. The presentation focuses on a new set of commands, which are biased to graphics useful for models predicting continuous response variables.
