Parafac
2 is the most flexible Simultaneous Component Analysis (SCA) model that produces an essentially unique solution …. In this paper, we discuss how
Parafac
2’s special sign indeterminacy affects applications of SCA, and we reveal how an … external criterion variable can be used to ensure that estimated
Parafac
2 weights are meaningfully signed across the levels of …
