Bayesian t-test median and 95% CI estimates

edited April 2019 in JASP & BayesFactor

Hi there,

I've ran some Bayesian independent samples t-tests in JASP, and found that the median and 95% CI estimates change very slightly each time I run the analysis. The two figures attached were the same analysis ran on the same data. Can anyone tell me why there's always a slight variation in these estimates please?

  • Hi Chris,

    The computation of these quantities requires a numerical procedure, and this comes with (very small) additional fluctuation.



  • Hi E.J., thanks for the response.
