This page, created by Richard Lowry of Vassar College, will perform a twoway factorial analysis of variance for designs in which there are two to four randomized blocks of matched subjects, with two to four repeated...
In the first simulation, random samples of size n are drawn from the population one sample at a time. With df=3, the critical value of chisquare for significance at or beyond the 0.05 level is 7.815; hence, any...
Richard Lowry of Vassar College has created a loglinear analysis which is a version of chisquare analysis. The relevant values are calculated by way of weighted natural logarithms. This page will calculate several...
The following pages calculate r, rsquared, regression constants, Y residuals, and standard error of estimate for a set of N bivariate values of X and Y, and perform a ttest for the significance of the obtained value...
This applet, created by professor Richard Lowry of Vassar College, calculates unweighted kappa and kappa with linear and quadratic weightings, along with some other measures of concordance. Lowry has provided the option...
