The following data 'psi31' are taken from Birnbaum and Saunders(1969).

Birnbaum, Z. W. and Saunders, S. C. (1969). Estimation for a family of life distributions with applications to fatigue. J. Appl. Probab. 6(2), 328-347.

Leiva, V., Hernández, H., and Riquelme, M. (2006). A New Package for the Birnbaum-Saunders Distribution.

The MLE's are obtained using 'bs' package in R    alpha.mle = 0.1703847 beta.mle = 131.8188
