This program calculates three indices of factor pattern invariance: coefficient of congruence (Rc); chi-square goodness of fit; and salient variable similarity index. All three require that the same variables and factoring methods be used in separate...
A standalone Windows program that interactively simulates how the 95% confidence interval and statistical significance (probability) of the correlation coefficient vary as a function of sample size. Change r and N and watch the probability and confidence...
A standalone Windows program that graphs the Receiver Operating Characteristic (ROC) curve and calculates the Area Under the Curve (AUC) using the nonparametric method presented by Hanley and McNeil (1982) that does not make any distributional assumptions...
A standalone Windows program that computes Parallel Analysis criteria (eigenvalues) to determine the number of factors to retain in a factor analysis by performing a Monte Carlo simulation. The user can specify 3-300 variables, 50-2500 subjects, and...
A standalone Windows program that calculates the chi-square statistic for 2x2 to 10x10 contingency tables. Also calculates the contingency coefficient, phi, and kappa statistics. The chi-square test is used to compare the distributions of two independent...
A standalone Windows program that calculates effect sizes (Cohen's d, r, Glass's delta, Hedges' Unbiased d, Common Language Effect Size, mean difference, pooled standard deviation) given appropriate group means and standard...
Estimates the sample size needed for a specified coefficient alpha, given the Type I error rate and the effect...
A standalone Windows program that calculates diagnostic efficiency statistics: sensitivity, specificity, false positive rate, false negative rate, positive and negative predictive power, odds ratio, kappa, likelihood ratio, odds ratio, phi...
Body Mass Index Calculator is an easily calculated index of body fat for adults that uses only height and weight. The formula used in this Calculator is (Weight in Pounds * Height in Inches squared) x 703. The definitional formula is Weight in Kilograms *...
