The congeneric reliability and standardized reliability; also the
bias b
so that omega
- alpha
= b
.
alpha_bias(sigma, lambda, w = rep(1, length(lambda)))omega(sigma, lambda)
omega_std(sigma, lambda)
alpha(sigma, lambda)
alpha_std(sigma, lambda)
The congeneric reliability standardized reliability, coefficient alpha, standardized, orsigma coefficient alpha.
For alpha
and alpha_std
, either apositive definite
covariance matrix or a vector of standard deviations. A vector of
standard deviations for omega
and omega_std
.
Vector of loadings.
