Wy. Tsai et Ch. Zhang, ASYMPTOTIC PROPERTIES OF NONPARAMETRIC MAXIMUM-LIKELIHOOD ESTIMATOR FOR INTERVAL-TRUNCATED DATA, Scandinavian journal of statistics, 22(3), 1995, pp. 361-370
In this paper, a nonparametric maximum likelihood estimator for a cond
itional lifetime distribution is considered for observations truncated
simultaneously from the right and left sides, and its almost sure uni
form convergence and asymptotic normality are established based on a s
elf-consistency equation.
