Powers, Stephen; Jones, Patricia – Educational and Psychological Measurement, 1986
This paper describes a computer program which tests all pairwise comparisons of adjusted means in analysis of covariance by using Tukey-Kramer Test. The program contains: means of covariate, adjusted means of the criterion measure, sample size, mean square error, and the desired percentile point on the Studentized range distribution. (JAZ)

Powers, Stephen; Gose, Kenneth C. – Educational and Psychological Measurement, 1986
A BASIC computer program is described which computes the Stuart-Maxwell test with its chi-square value and associate probability level. Following a significant chi-square test, the user has the option of performing multiple comparisons using McNemar's test for the significance of change. (Author)

Powers, Stephen; Jones, Patricia B. – Educational and Psychological Measurement, 1986
This paper describes two BASIC computer programs that calculate Hotelling's T-square either for one sample or for two samples. Output of the progams includes the Mahalanobis distance D-square, the F ratio associated with T-square, and its probability level. (Author)

Powers, Stephen – Educational and Psychological Measurement, 1984
This paper describes a microcomputer program that extracts principal components from a correlation matrix and rotates them to a varimax solution. Eigenvalues, variances associated with each component, unrotated component loadings, and varimax rotated loadings are output by the program. (Author)
