Description

NNETAR currently normalizes the response variable. This is ok when linout=TRUE, but when linout=FALSE, a logistic activation function is used and the response is assumed to be binary. So it should not be normalized.

Research direction

Start by locating the NNETAR implementation and read how response normalization depends on linout. Verify that normalization is skipped when linout=FALSE while preserving the current behavior for linout=TRUE; add or update coverage for both cases if the relevant tests are found.
