Do anybody know where the description of the data set, SASHELP.PRDSAL and other two related data sets(PRDSAL2, PRDSAL3) is given? There are two variables, ACTUAL and PREDICT. They refer to furniture sales and predicted sales. How PREDICT is computed and what goes behind?
I appreciate your help.
I guess there's no formula behind the PREDICT values. They are just set more or less arbitrarily to have material for analysis.

Thanks for your reply.
I am wondering whether these PRDSALE and other two are used in SAS Documents to know in which context they are used. Otherwise I am not seeing any description of the data sets.
Treat the data as something collected by the government or other large client that either won't or can't tell you how the raw values were compiled.
The SAS supplied data sets were constructed to use for example analysis. So values may well have been picked to allow/demostrate the results of different options for specific analysis procedures. If the labels on the variables are not sufficient I am not sure what you want.
As a brief example the SASHELP.Iris dataset is used to demonstrate graphing procedures G3D,SGPANEL, SGPLOT,SGSCATTER,; used in examples for Procs ACECLUS, CANDISC, CLUSTER, CORR, DISCRIM, FASTCLUS, STEPDISC and TREE.
If you installed the online help you can likely search for the dataset name to find a similar list for each of the sets.
