gamlj: Normality test (Sample size must be between 3 and 50K

Discuss statistics related things

Hello,

I was trying to perform a Residuals test of normality for linear mixed models (gamlj, 2.30), Jamovi 1.6.18.0 on MacOS 11.2.2,

I was able to get the Q-QPlot of residuals and Residual histogram.

The only issue is when I requested the "Test Normality of Residuals". I get the following error (see screenshot): "sample size must be between 3 and 5000. I am not clear as to what the issue is since my sample size is clearly more than 20.

and the Assumption Check Box is empty.

Thanks!

Roberto

Nice bug you found! This is due to R function `shapiro.test()` which does not allow to test more than 5000 cases. I put a check in the code so in those cases it does not stop the rest of the computations.
thanks for helping

Dear Marcello,

I am glad I found it. I am assuming it will be fixed for the next version.

Thanks!!
