FD {BifactorIndicesCalculator}

Factor Determinacy

Description

FD computes factor determinacies for all factors provided standardized factor loadings and an interfactor correlation matrix.

Usage

FD(Lambda, Phi)

Arguments

Lambda

is a matrix of standardized factor loadings

Phi

is the matrix of factor intercorrelations. For bifactor models Phi is diagonal with ones on the diagonal.

Details

FD is called by bifactorIndices and the various convenience functions for exploratory models and/or Mplus output, which are the only functions in this package intended for casual users.

Value

a vector of factor determinacies.
