Adding table with posterior means/medians and credibility intervals + clarifying content of descriptive plots for Bayesian ANOVA #195

Closed vciocca closed 8 months ago

vciocca commented 6 years ago

Template for enhancement requests

* Enhancement: Clarify contents of the descriptive plots and add a table displaying posterior means (or medians) and credibility intervals * Purpose: Neither in the existing documentation (e.g., the Wagenmakers et al, 2016 article on JASP that was published on the Psychon Bull Rev) nor in the software itself, there is a clear indication that the descriptive plots whether the descriptive plots display features of the posterior distribution. The fact that one can choose to display "credibility" intervals would lead one to believe that this is the case. However, the plots look virtually identical to those one obtains from the classical ANOVA, displaying confidence intervals.. It would also be helpful, in addition to plots of posterior means/median and credibility intervals, to be able to obtain a table with numerical values from the posterior distribution. Thank you for considering this request, and for the good work made so far. Valter

Hi Valter,

Thanks for the suggestion. The credible intervals in the descriptive plots are based on Jeffreys's parameterisation invariant priors used for estimation. I'll give the documentation project a bump.

Cheers, Alexander

Just a follow up question on this @AlexanderLyNL - the (observed) means and credible intervals in the descriptive plots are the same as the ones obtained from the 'Descriptives' check box during the analysis, correct?

Is there a possibility to get this table only for a certain factor (e.g., only for factor A - averaged over factor B and C - instead of A B C in a 3 way design) as can be done with the plotting?
