Presents the first goodness-of-fit test for independent component models with asymptotic validity in high dimensions without pre-whitening.
Next, since we have Pp j=1 Σ2 jj ≳punder Assumption 1, it follows from Lemma 1 that Pp j=1 Σ2 jj Pp j=1 ˇΣ2 jj =O P(1) and Pp j=1 Σ2 jj − ˇΣ2 jjPp j=1 Σ2 jj =O P( 1 p)
