摘要:
The asymptotic distributions of Cramer-von Mises type statistics based on the product-limit estimate of the distribution function of a certain class of randomly censored observations are derived; the asymptotic significance points of the statistics for various degrees of censoring are given. The statistics are also partitioned into orthogonal components in the manner of Durbin et Knott. The asymptotic powers of the statistics and their components against normal mean and variance shifts, exponential scale shifts, and Weibull alternatives to exponentiality are compared. Data arising in a competing risk situation are examined, using the Cramer-von Mises statistic. An important problem in the analysis of survival data is whether the observed survival pattern for a cohort of individuals can be closely explained by a particular mathematical model with readily interpretable characteristics.
