M.Korhonen 1992 With the MTAB operation you can construct a quite large range of tables for frequencies, means and other descriptive statistics. The general form of the MTAB operation is MTAB <data>,L VARIABLES or IVARIABLES=<list of object variables> GROUPING=<list of grouping variables> <definitions for grouping variables> COL=<column layout> ROW=<row layout> OPTIONS=<options for statistics> The parameter L (optional) gives the starting line for the results in the edit field. Variables, for which means or other statistics are to be computed, are listed in VARIABLES or IVARIABLES specification. The latter is used for dichotomous object variables. The GROUPING specification defines variables that are used as grouping (class) variables. The final layout of the tables may defined by COL and ROW specifications.
