Published in 2017 at "Journal of Statistical Computation and Simulation"

DOI: 10.1080/00949655.2017.1331441

Abstract: ABSTRACT A general procedure is developed for bias-correcting the maximum likelihood estimators (MLEs) of the parameters of Weibull regression model with either complete or right-censored data. Following the bias correction, variance corrections and hence improved… read more here.

Published in 2018 at "Communications in Statistics - Theory and Methods"

DOI: 10.1080/03610926.2018.1472784

Abstract: Abstract In this study, adjustment of profile likelihood function of parameter of interest in presence of many nuisance parameters is investigated for survival regression models. Our objective is to extend the Barndorff–Nielsen’s technique to Weibull… read more here.

Published in 2023 at "Biology"

DOI: 10.3390/biology12030442

Abstract: Simple Summary This article proposes a comparative study between two models that can be used by researchers for the analysis of survival data: Weibull regression and random survival forest. The models are compared considering the… read more here.
