Hi,
I tried to run a 2 ways Anova and jamovi returned an error message when I asked for the post-hoc test: "Perhaps a 'data' or 'params' argument is needed". I don't know if it helps, but, out of curiosity, I ran it in Jasp and it worked well. See file in attachement.
Have a nice day!
[SOLVED] 'data' or 'params' argument is needed

It doesn't seem to like the spaces in the variable names. I'll fix this for our next release. For now, you can remove the spaces from "nbr de bieres" to make the post-hoc tests work. Could you also post this issue on our github so we can keep better track of it? Thank you for reporting this and have a nice day too

Hi,
I encountered this very same error message but in a non-recurring way.
On some computers, the dataset works fine and the anova + pocthoc are performed flawlessly but on other machines, it returns the error message in the title. It only happens when a post-hoc test and/or a estimated margial mean is/are computed. The anova alone works fine.
It happens with W10 and iOS and with both solid and current versions.
If it can help, when I open the .omv file attached with the precedent message,the error message occurs but when I copy/paste the dataset in a new .omv file, everything works perfectly.
Thank you, have a nice day.

So I found the cause of the issue: there's a trailing space after the Niveau variable. If you remove that space it works fine again. Of course, this still shouldn't result in an error, so I'll look into a fix for this problem. Thanks for reporting!

hmm, so our import/open pipeline *should* strip spaces from the beginning/end of values. i wonder if we shouldn't treat this as a bug in our io system?

do you have the original data file you opened for this data set romaric?
i want to figure out how the data got in there without the spaces being stripped.
with thanks
