In this study, inference for the power Lindley distribution under a step-stress partially accelerated life test based on progressive Type-II censoring scheme is studied. The maximum likelihood estimates of parameters and acceleration factor investigated with their corresponding approximate confidence intervals by using asymptotic theory. performances estimators are evaluated simulation studies....

Quantile regression has been advocated in survival analysis to assess evolving covariate effects. However, challenges arise when the censoring time is not always observed and may be covariate-dependent, particularly in the presence of continuously-distributed covariates. In spite of several recent advances, existing methods either involve algorithmic complications or impose a probability grid. ...

In medicals sciences and reliability engineering, the failure of individuals or units (I/Us) occurs due to independent causes failure. general, symmetry between dependent is essential nature problem at hand. this study, we considered accelerated competing risks model when lifetime I/Us was modeled using a generalized half-logistic distribution. The data were obtained with respect constant stres...
