CSELECT — Selects cases (groups), generate learn/test samples

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.

Fig. 14: Voice sound characteristics possess a distinct "individuality" that allows one, for example, to identify persons on the phone very quickly without speaking explicitly about the identity of the speaker. In fact, voice sound characteristics have a strong biological component in the range of 80% or higher. The inter-individual differences of voice sound patterns between unrelated subjects can be studied in detail by means of a similarity function that quantifies between-subject similarities and dissimilarities as a function of frequency (here: comparison of two repeated assessments of the same subject at 14-day intervals). See Fig. 13 for a comparison of unrelated subjects.
