Confidence intervals estimation for survival function in weibull distribution based on censored survival time data

28281

Weibull distribution plays an important role in the analysis of survival or life time data. Previousarticles presented a confidence interval estimate of survival function using Cox’s proportional hazard model with covariates. The idea is more recently extended to the exponential distribution and exponential proportional hazard model, respectively. The same idea may be extended to the Weibull distribution which provides that the survival times have a Weibull distributed with random variable. In this study, we formed confidence interval for Weibull survival function in any values of the survival time in the data. Real time data examples are also considered for the discussed confidence intervals.
