Hello, I am using melogit to run a mixed-effects logistic regression. My code took a very long time to run and then finished with the following error, which I do not understand and am having trouble finding any information on:

This is the line of code I am running:
My LHS variable is a 0/1 binary variable; when I run the same command with "mixed" (i.e.,
), I have no issue at all.
I am quite mystified by what this means -- any guidance or thoughts would be greatly appreciated. Thank you very much!
This is the line of code I am running:
Code:
melogit choseP1 *diff i.encodechar* if view == 1 || scenario: *diff
Code:
mixed choseP1 *diff i.encodechar* if view == 1 || scenario: *diff
I am quite mystified by what this means -- any guidance or thoughts would be greatly appreciated. Thank you very much!
