OMNIDATA:An Interactive System for Data Retrieval,Statistical and Graphical Analysis,and Data-Base Management. A User's Manual,

摘要

The Omnidata system,consisting of 45individual programs written in XBASIC,provides an interactive user-oriented facility for:data retrieval and report generation;plotting and other graphical analysis;arithmetic and statistical analysis;curve fitting and multiple linear regression;data coding and decoding;survey and questionnaire analysis;author,title,and keyword indexing of bibliographic files; a variety of univariate analyses and two-way crosstabulations;and numerous utility modules for file definition,file updating,and file maintenance. The SEARCH module which performs a serial search through a file allows for:the usual Boolean operations;string searching on text fragments,stems,or roots in either the anchored or unanchored mode;specification of syntatical order and proximity of words or phrases,as well as variable length ellipsis;and ignoring one or more of a specified list of characters in its matching operation. Four of the modules interface with the OMNITAB II system for versatile plotting,very accurate least-squares fitting,and a comprehensive statistical analysis.
