Basic Analysis Commands

The commands described in this chapter can be used to carry out simple summary analyses of the current data set. Basic analysis commands include sums, means, frequency tables, and the computation of ranks and percentiles. Commands that can be used to display character-based plots and histograms are also discussed. The DATA command produces text files containing some or all of the variables in the current data set. This command can be used in conjunction with the SELECT command to produce data sets containing only a subset of the current data set. The analysis, plotting, and listing commands can be used only after the data have been read. This chapter also includes descriptions of commands that can be used (at any time) to compute normal and  P-values.
