Abstract: | This report describes an APL system for file-oriented univariate analysis, correlation, and regression analysis. The correlation and regression processes permit analyses of an unlimited number of cases, if the cases are arranged in tables small enough to be processed one at a time in a workspace. Support functions are also given for a menu-based processing system designed to support a broad range of analyses. The functions offer features such as subset selection, data transformation, and exclusion of invalid items. |
