On the Bayesian estimation for Cronbach's alpha

What is it about?

This article considers the problem of estimating Cronbach’s alpha under a Bayeisan framework. Such Bayes estimator arrives through out approximating distribution the maximum likelihood estimator for Cronbach’s alpha by an F distribution. Then, employing a non informative prior distribution, Bayes estimator under squared-error and LINEX loss functions have been evaluated. Simulation studies suggest that the Bayes estimator under LINEX loss function reduce biasness of the ordinary maximum likelihood estimator. Moreover, The LINEX Bayes estimator does not sensitive with respect to choice of hyperparameters of prior distribution. R codes for readers to calculate Bayesian Cronbach’ s alpha have been given.
