This blog post explains how you, as a JASP user, can help improve the program — simply give us feedback whenever something is amiss. Specifically, whenever you notice that JASP cannot execute an important task (e.g., filter cases), you can tell us by issuing a feature request; whenever you notice that JASP malfunctions in some way (e.g., the font size…

Network analysis is a relatively new and promising method for modeling interactions between large numbers of variables. Instead of trying to reduce the structure of the variables to their shared information, as is done in latent variable modeling, we estimate the relation between all variables directly. In this blogpost, we provide a short tutorial on how to do network analyses…

The analysis of categorical data has a long history and can be traced back to some of most influential statisticians: Karl Pearson and Sir Ronald Fisher. In 1900, Pearson first introduced the -statistic and thus the initial versions of the now known multinomial test and goodness-of-fit test. Today, the multinomial test and the goodness-of-fit test have become a standard procedure…

Soon we will release JASP 0.8.6. In this post we preview three important new features. 1. Frequentist Multinomial and Chi-Square Tests JASP 0.8.6 provides frequentist multinomial and chi-square tests. For count data, users can test whether the cell frequencies are equal (i.e., the multinomial test), but users are free to specify any pattern of expected frequencies (or probabilities) and test…

When trying to fit a regression model where the dependent variable is categorical, logistic regression is the weapon of choice. Implemented in JASP 0.8.3, logistic regression just got some nice upgrades in the latest version of JASP, 0.8.5. Logistic regression makes it possible to analyze and learn from data if your outcome variable is categorical in nature, such as whether…
