Question: Let x = (x1, . . . , xn1) and censored observations (xn1 +1, . . . ,xn) (that is, ith experiment, if I >

Let x = (x1, . . . , xn1) and censored observations (xn1 +1, . . . ,xn) (that is, ith experiment, if I > n1, the survival time is at least yi). Let the new complete censored data yi be such that

Let the mean survival time be Î¸ and the probability density of y be

and let the survival function be defined as the probability that an individual survives beyond time y, that is, S(y) = P(Y > y). Thus,

(a) Obtain the MLE, Î¸-capM:
(b) Obtain an EM algorithm.
