Query: On optimal allocation of treatment/condition variance in principal
  component analysis   The allocation of a (treatment) condition-effect on the wrong principal
component (misallocation of variance) in principal component analysis (PCA) has
been addressed in research on event-related potentials of the
electroencephalogram. However, the correct allocation of condition-effects on
PCA components might be relevant in several domains of research. The present
paper investigates whether different loading patterns at each condition-level
are a basis for an optimal allocation of between-condition variance on
principal components. It turns out that a similar loading shape at each
condition-level is a necessary condition for an optimal allocation of
between-condition variance, whereas a similar loading magnitude is not
necessary.
