Repeated Measures ANOVA with missing values

Hi,

I have seen in this post (https://forum.cogsci.nl/discussion/6962/repeated-measures-anova-missing-data) that missing values are apparentely not a problem when running a RM Bayesian ANOVA. However, looking to my ANOVA output I am not quite sure that's the case:

So, the descriptives are being calculated for 4 participants (e.g., those with data in all conditions) when the total number of participants is 20. I am wondering whether the RM ANOVA is also being calculated for those 4 participants only, which is not what I want.

Any advice would be very much appreciated!

  • I can't remember the exact thread, but I was told that in JASP "repeated-measures" Bayesian ANOVA is not really repeated-measures ANOVA but is instead a linear mixed-effects model--EXCEPT that it excludes rows containing missing values, the way RM-measures ANOVA would.

  • Hi, thanks for the comment. Apparently the Bayesian RM ANOVA does the listwise deletion of missing values.

    An alternative to this would be to do a Bayesian Linear Mixed Model, but with that analysis you don't get a Bayes Factor. So, I can't see a clear solution to this problem at the moment.
