Bug Description

I was trying to create interactions in the meta-analysis. It worked for one interaction but it does not anymore. If I now erase that interaction and then try to do it again it will show Error: Non-existent coefficients specified via 'btt'

Expected Behaviour

Should let me do the interactions

Steps to Reproduce

1. Go to model in the meta-analysis
2. choose the interaction
3. apply
4. bug will show
   ...

Log (if any)

thx for the report. I cannot replicate the error, see:

Can you share your data by renaming to zip and drag and drop here?
Maybe you have some missings or otherwise unconventional data.

[tomtomme]

maybe you just need to change your "weaning age weeks" var to scale and refresh?

Hello, Thank you for the reply. How do I share my data? It doesn't give me an option to rename to zip.

Just rename the File in a File Explorer.

I can confirm the error. Maybe the interaction of milkType * Category has to many empty cells? See:

Here the jasp file (renamed) to replicate the error:

meta.jasp.zip

But also the effect size "daily weight gain" seems suspicious. Isn't it a requirement to use standardized effect sizes here like cohens d or pearsons r?

[nkotler21]

Okay, that makes sense. Thank you. As for effect size, I was under the impression I could use my actual data for it rather than effect size. Effect size is supposed to be calculated through the meta-analysis? Do you suggest then to calculate each effect size separately and then do the meta-analysis?

Never mind. I just read in the jasp help file of the "effect size computation" module that you also can input unstandardized effect sizes like mean differences. If jasp later on can standardize this within the main module meta analysis - I do not know. But it sounds probable.
