Interval-Censored Survival Analysis: A Comparative Monte Carlo Study of Weibull AFT and Cox Proportional Hazards Models

Axioms
This study investigates the comparative performance of the Weibull accelerated failure time (AFT) model and the Cox proportional hazards (PH) model for interval-censored Weibull data.

The Beta Weibull-G Family of Distributions: Model, Properties and Application

, 2018
A new family of generalized distributions called the beta Weibull-G (BWG) distribution is proposed and developed. This new class of distributions has several new and well known distributions including exponentiated-G, Weibull-G, Rayleigh-G, exponential-G,

On the Weibull distribution

, 1976
This work involves the comparisons of various estimates of the parameters of the Weibull distribution. These estimates have been obtained by using various statistical techniques, such as the method of maximum likelihood estimation, the method of moments,

Omitted variables in a weibull regression model

, 1984
Asymptotic biases of maximum likelihood and least squares estimators in a Weibull model, subject to omitted variables, are given. The results are contrasted to those of a small sample Monte Carlo experiment.
