Hi everyone,
I recently posted a question about HCPC giving out different results with each run, but I've come to realize that the problem is not with HCPC but with MCA, and particularly with level.ventil:
One of my variables contains several very infrequent categories, and ventilating these categories seems to be what's causing the problem. When level.ventil=0 the MCA results are consistent every time, but when level.ventil>0 I get different results with each run, even though the code remains exactly the same.
I guess I don't fully understand what ventilation actually does... Any suggestions?
