curprev 10:1410:14, 6 December 2024 141.70.80.5 talk 26,176 bytes +41 I looked it up in the book and the statement is not right the way it was formulated. It depends on the estimator of the covariance. Of course, if one assumes gaussianity then one is not able to capture any non-gaussianities, which is here described as non-linearities. This if for example wrong if one considers the full integral at the beginning. In this case one would capture also non-linear effects. undo

Also I don't believe it is called "lag factor", but rather should just be called "lag". The word "factor" is usually reserved for when there is a multiplicative relationship. undo Tag: Visual edit
