SPAN REFERENCE MANUAL. SPAN DATA-TRANSFORMATIONS AND STRATIFICATION CAPABILITY

Abstract

This document is one of a series of volumes of the SPAN REFERENCE MANUAL describing the SPAN system for data management and statistical analysis. The SPAN system provides an integrated file processing and multivariate analysis capability for problems involving large data matrices with large numbers of variables. The system is oriented to problems of social science in general and urban data analysis in particular. This volume describes the specification and use of SPAN capabilities for the transformation of the contents of a data file in the course of its input to a SPAN process. The data-transformation capability allows the user to state algorithmic procedures leading to the generation of new data variables as transformations of the source data. The entity stratification capability provides for the classification and selection of entity records according to user-specified criteria.
