Trend Analysis Using Microcomputers.
Berger, Carl F.
A trend analysis statistical package and additional programs for the Apple microcomputer are presented. They illustrate strategies of data analysis suitable to the graphics and processing capabilities of the microcomputer. The programs analyze data sets using examples of: (1) analysis of variance with multiple linear regression; (2) exponential and higher order regression; (3) orthogonal tests of trend; and (4) the use of dummy variables to handle categorical variables. Microcomputer benefits and limitations are highlighted with the exploratory analysis techniques. An example of a traditional analysis of variance test is presented which illustrates the microcomputer data entry procedure. Graphic displays of program statements and diagrams are included with an appendix of sample programs. (CM)
