JASP is a cross-platform software program primarily developed for Bayesian analyses. It currently utilizes more than 50 R packages and provides an intuitive & user-friendly GUI (graphical user interface). However, unfortunately the generated R code cannot be exported. This …
Model comparison via Bayes Factor analysis
Results of Bayesian analyses can be utilised for future research in the sense of Dennis Lindley’s motto: “Today’s posterior is tomorrow’s prior” (Lindley, 1972), or as Richard Feynman put it “Yesterday’s sensation is today’s calibration” to which …
Bayesian correlation coefficient
• ρ (rho): The correlation between experimental condition V00 and V10
• μ1 (mu[1]): The mean of V00
• σ1 (sigma[1]): The scale of V00, a consistent estimate of SD when nu is large.
• μ2 (mu[2]): the mean of …
Bayesian parameter estimation supersedes t-test
The Bayesian inferential approach provides rich information about the estimated distribution of several parameters of interest, i.e., it provides the distribution of the estimates of μ and σ of both experimental conditions and the associated effect sizes. Specifically, the method …
