There is a typo in my edition of the book. I wonder whether that typo is the source of your problem. The typo is that the variable names of the predict statement is different from the variable name of the commands that follow. If you have Stata 8, the following command work as in picture at page 172 use http://www.stata-press.com/data/lfr/ordwarm2.dta, clear ologit warm yr89 male white age ed prst, nolog predict SDwarm Dwarm Awarm SAwarm label var SDwarm "Pr(SD)" label var Dwarm "Pr(D)" label var Awarm "Pr(A)" label var SAwarm "Pr(SA)" dotplot SDwarm Dwarm Awarm SAwarm, ylabel(0(.25).75) ysize(2.0124) xsize(3.039) The other possible cause of your issue is that you are using the version of the book written for Stata 7 and using Stata 8. If so you can continue to use the commands as they are written in your book, but you must put -version 7- at the beginning or your do file (or -version 7:- before the commands that do not work). If this does not help you, please post the exact commands you use to generate the graphs and the first two lines of the output of the -about- command.

I followed chapter 5 in Long's book (Regression models for categorical and limited dependent variables). As for now, I am able to calculate all marginal probabilities at min, max, and average values but I can't produce predicted and cummulative probabilities graphs as in Figure 5.3. thanks , Phuong * * For searches and help try: * http://www.stata.com/support/faqs/res/findit.html * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
