calculateVIFModeB: Calculate variance inflation factors (VIF) for weights obtained by PLS Mode B

Description

Calculate the variance inflation factor (VIF) for weights obtained by PLS-PM's Mode B.

Usage

calculateVIFModeB(.object = NULL)

Arguments

.object

An R object of class cSEMResults resulting from a call to csem().

Value

A named list of vectors containing the VIF values. Each list name is the name of a construct whose weights were obtained by Mode B. The vectors contain the VIF values obtained from a regression of each explanatory variable of a given construct on the remaining explanatory variables of that construct.

If the weighting approach is not "PLS-PM" or for none of the constructs Mode B is used, the function silently returns NA.

Details

Weight estimates obtained by Mode B can suffer from multicollinearity. VIF values are commonly used to assess the severity of multicollinearity.

The function is only applicable to objects of class cSEMResults_default. For other object classes use assess().
