NAN in post-hoc test

Dear JASPers, I am doing a repeated measures ANOVA analysis, but for some reason many (but not all) of my post-hoc tests show a mean difference, a SE, a statistic, but then a NaN for the p-value (see below).

Could you please help me understand why there is a NaN?

thank you



  • sorry, I now saw a similar post. I ran my analysis on 0.9.1, so I'll try it on 0.9.2 and re-post if needed (sorry!) :-)

  • Dear All,

    still got the NaNs above in 0.9.2. Any advice?



  • Hi Martin,

    I'll ask the expert in our team. We are nearing a new version, so it would be great to see this fixed (if it is a bug).

  • Hi Martin,

    Due to the Scheffe and Tukey corrections not being suitable for RM factors, we have decided to not display those and clarify this with a footnote in the table. However, I will change the way it is being displayed, since NaN is ususally an indicator that something went wrong in the analysis.

    For now, I would advise you to use another p-value correction, such as Bonferroni or Holm.

    Kind regards,
