WebPartial least squares is one of a number of covariance-based statistical methods which are often referred to as structural equation modeling or SEM. It was designed to deal with multiple regression when data has small sample, missing values, or multicollinearity. Partial least squares regression has been demonstrated on both real data and in Webdimension reduction step is incorporated in the Cox regression step. This paper is organized as follows. The Methods section is the methodological part of this paper. It contains a …
