Jasp - Bayesian Repeated Measure ANOVA - between subject factor

tommasocurro

Hello,

I am trying to run a Bayesian Repeated ANOVA in JASP for Reaction times in a Go/Nogo task. I would like to insert a between-subject factor (right-left, coded as 1-0), unfortunately I get the error copied below. Before getting the error, the results of the analyses appear at this between-subject factor is very important (BF10 = 2539.87). One problem with the data is that there is an uneven number of participants (39vs40) in the two groups (corresponding to the between-subject factor). Infact, when I remove a participant the analysis works. How can I solve this issue without randomly eliminating one participant to make them even?

Thank you,

This analysis terminated unexpectedly.

Hi Tom,

That is really strange and almost seems more like a bug. I'll attend the team to this but you could also post this issue on our GitHub page (for details see https://jasp-stats.org/2018/03/29/request-feature-report-bug-jasp/)

Cheers,

E.J.
