GSELECT — Selects grouped cases, repeated assessments, conditions

This program is used to define a subsample of cases for subsequent analyses. Cases are selected through the specification of study-numbers, group-numbers, proband-numbers, recording days, and experimental conditions. A sequence of CSELECT-calls accumulates cases, so that any problem-specific subsample of cases can be assembled by a sequence of single steps. An existing subsample of cases is deleted by means of the parameter RSET.
