FD: Factor Determinacy
In BifactorIndicesCalculator: Bifactor Indices Calculator

Description Usage Arguments Details Value See Also Examples

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

1	FD(Lambda, Phi)

`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.

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.

a vector of factor determinacies.
