Eigen Decomposition Error #1

Open DarioS opened 3 years ago

DarioS commented 3 years ago

Error in eigen decomposition for variable 2469, this variable was not normalised.

Is there anything the user should do or is it unavoidable? Could it be mentioned in the function's documentation?

This is unavoidable. The only thing you can do is reduce k, find more non-missing values of that variable, or find more samples.

The issue relates to variables which don't have sufficient replication to support the estimation of the number k of factors of unwanted variation. I will add it to the documentation of both functions.
