The congeneric reliability and standardized reliability; also the
bias b so that omega - alpha = b.
Usage
alpha_bias(sigma, lambda, w = rep(1, length(lambda)))
omega(sigma, lambda)
omega_std(sigma, lambda)
alpha(sigma, lambda)
alpha_std(sigma, lambda)
Arguments
- sigma
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.
- lambda
Vector of loadings.
Value
The congeneric reliability standardized reliability,
coefficient alpha, standardized, orsigma coefficient alpha.
