Thanks again for your Melbourne workshop!
I've been running the NIPALS function on my own data. I have two datasets which are slightly different subsets of a larger dataset that have a large overlap and similar distributions (see summary 1 and 2 attached). When I run nipals on my second dataset I get reasonable imputed values however for the first dataset I get wildly out of range imputed values (see NIPALS 1 and 2 attached). There are quite a few more missing values in the first dataset, would this be what is causing the issue?
