JASP-data are essentially constant
I am trying to run a repeated-measures ANOVA on a set of data with two independent factors.
When I try to run the analysis JASP returns the following message "data are essentially constant".
I understand that this is due to the fact that there is not much variation in the data. The problem is that I still need to run the analysis in order to get an output so that I can show that data really are essentially constant. I read that there is some way around this problem in other statistics software, I was wondering if this can be done in JASP as well.
By the way, if I run a regular ANOVA with two independet factors I get no error message. Why is that?
Thank you all for your help
