A GENERAL FORTRAN PROGRAM FOR LEAST-SQUARES ANALYSIS OF VARIANCE,

Abstract

The report describes a computer program written in FORTRAN language designed to be used for the majority of least-squares analysis of variance computations. The program is completely general in the sense of its ability to handle any size of factorial-type of design. A user's control card sets the number of factors, k, and the maximum number of levels per factor. Interaction sums of squares may be obtained to a maximum depth of k-1. In computing the sums of squares for a category of variance, the number of observations are counted concurrently with the summing of them. This allows for analysis of experiments with missing data and for unbalanced designs in which no observations may exist at certain levels of some factors without the need for artificial techniques for estimating the missing data. The program consists of three main parts; initialization and input of observations, computations of raw (uncorrected) sums of squares, and correction of raw sums of squares and output. The user is required to write his own input subroutine which interfaces the user's input card file with observation storage of the main program. (Author)
