Hi there,

Understand that the bootstrapping method used by SmartPLS is following Efron and Tibshirani, 1986 and Davison and Hinkley, 1997. There are two main methods for regression bootstrapping mentioned in those texts - pair bootstrap and residual bootstrap. Would like to know which of these two is the one used by SmartPLS.

Thank you.

There are many different versions of bootstrapping described in these texts, but what PLS algorithms rely on (not only SmartPLS) is usually a simple case bootstrap. That is resampling entire cases (i.e., observations, rows) of the data matrix with replacement.
