Randomized trial analyzes survival times using exponential and Weibull hazard functions, indicating improved inference methods.

This research aims to analyze survival times and derive significance tests for covariate parameters in survival data.
Analyzed survival times with exponential hazard functions that vary with covariates and are constant otherwise.
Derived probabilistic inference for hazard functions at average covariate values.
Extended analysis to include a Weibull component in the hazard function.
Identified significant effects of covariates on survival times.
Demonstrated improved statistical inference methods for hazard functions with average covariates.
Applied findings to clinical trials on advanced lung cancer patients.
