Volume Testing of Statistical Systems

This paper outlines the steps taken to solve data management and analysis problems based on two complex files. One file, TRIPS, contained four groups of variables in a three-level hierarchical structure resembling that of the 1972 National Travel Survey. The second file, PERSONS, contained records in which link variables defined relationships to other records in the file. Both problems were solved using the current implementation of OSIRIS at the University of Michigan. The solution to the problems based on the TRIPS dataset involved use of OSIRIS structured file creation and retrieval procedures. The solutions to the problems based on the PERSONS dataset were based on the use of OSIRIS sort and merge procedures. OSIRIS instructions and the cross-tabulations that resulted are presented for all four problem segments.
