This chapter uses the statistical software SmartPLS 3 (https://www. 20 It does this by using SVD to determine the inertia (i.
Two different formulations for partial least squares are available: the original method of Wold (1966) and the SIMPLS method
click over here of de Jong (1993). The equation of the PLS regression model writes:Y = ThCh + Eh = XWh*Ch + Eh = XWh (PhWh)-1 Ch + Ehwhere Y is the matrix of the dependent variables, X is the matrix of the explanatory variables.

PLS 1 corresponds to the case where there is only one dependent variable.

A common goal of PLS-SEM analyses is to identify key success factors and sources of competitive advantage for important target constructs such as customer satisfaction, customer loyalty, behavioral intentions, and user behavior. This is a preview of subscription content, access via your institution. A.
PLS is used to find the fundamental relations between two matrices (X and Y), i.
How To Without Time-To-Event Data Structure

predictor variation. Most of them construct estimates of the linear regression between X and Y as

. 67 In doing so, it maximizes the amount of variance explained (though what this means from a statistical point of view is unclear and PLS-PM users do not agree on how this goal might be achieved). 14
A PLS version based on singular value decomposition (SVD) provides a memory efficient implementation that can be used to address high-dimensional problems, such as relating millions of genetic markers to thousands of imaging features in imaging genetics, on consumer-grade hardware.
