Birnbaum-Saunders fatigue life distribution%multiply Type-Ц censoring%quasi-least squares estimation%approximate maximum likelihood estimation
In present paper, we derive the quasi-least squares estimation(QLSE) and approximate maximum likelihood estimation(AMLE) for the Birnbaum-Saunders fatigue life distribution under multiply Type-Ц censoring. Furthermore, we get the variance and covariance of the approximate maximum likelihood estimation.
