calculateVIFModeB.Rd
Calculate the variance inflation factor (VIF) for weights obtained by PLS-PM's Mode B.
calculateVIFModeB(.object = NULL)
An R object of class cSEMResults resulting from a call to csem()
.
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
.
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()
.
