I have been trying to use SNOWIRT to make some IRT models with my data since I have too many cases and I cannot use IRTPRO which is what I would normally use.
When I use my data, I get this message
. It doesn't matter which of my items I use." from" must be a finite number"
I already tried deleting the subjects with missing values, changing the measure and data type of all the variables, and I still get the message. I don't know what could be happening since a friend of mine has used Jamovi with large data before and hasn't had any problems.
I have approximately 3984 cases when I don't delete the cases with missing values, and 2091 when I delete the cases with missing values. I also tried to significantly reduce my sample but that didn't resolve the problem.
I bet is something with my data but I can think what It could be.
Any ideas?
