I have data like this below and I want to perform Meta Analysis in Major as follows below, but got an error: The condition has length >1.
Why is that, please help. I have tried Jamovi newest versions stable and experimental.
Kind regards,
Andrzej

hi,

this is a known issue. the maintainer of MAJOR has been missing for some time, and so far progress to address this issue has been slow going.

sorry we don't have better news.
