Raykov's factor reliability coefficient

This function computes Raykov's reliability coefficient (RRC) for factors from confirmatory factor analyses, a measure which is commonly seen as a more accurate one than that of Cronbach's alpha which is computed based on the assumption of tau-equivalent measures. It computes reliability coefficients for factors with and without correlated errors.
