Press Statistic

How may I perform a "leave-one-out" validation with a specified regression model and data set in SAS? This is associated with Weisberg (1985) and the PRESS procedure.

Check out the PRESS option, in the MODEL statement of the REG procedure. this is related to creating a dataset with coefficients in it (primarly for use in the Score procedure).
[pre]
PROC REG DATA = sashelp.class OUTEST = work.estimates ;
MODEL weight = height age / PRESS ;
RUN ; QUIT ;
PROC PRINT LABEL NOOBS ;
RUN ;
[/pre]
I don't know if there are equivalents in GLM, LOGISTIC, GENMOD or GLIMMIX procedures (if so, I haven't used them).

Is there a way to print out the individual press residuals?

PROC REG DATA = sashelp.class OUTEST = work.estimates ;
MODEL weight = height age / PRESS ;
RUN ; QUIT ;
PROC PRINT LABEL NOOBS ;
RUN ;
