A profile likelihood inference is made for the regression coefficient and frailty parameters in the correlated gamma-frailty model for current status family data. With the introduction of an identifiability assumption, the identifiability of the parameters and the existence of the nonparametric maximum likelihood estimate (NPMLE) are established, the consistency and convergence rate of the NPML...

Introduction: The aim of this study was to investigate the initial electron beam parameters for Monte Carlo model of 6MV photon beam produced by Siemens Oncor® linear accelerator.   Materials and Methods: In this study, the EGSnrc Monte Carlo user codes BEAMnrc and DOSXYZnrc were used. The beamnrc code were used for modelling of a 6 MV photon beam produced by...

the nondestructive techniques are applied to identify important data from the internal process of distillation towers, process towers, pressure vessels and etc. in recent, the gamma-ray scanning techniques as diagnostic tools for scanning of tray columns, packed columns, storage tanks, level measurement and density measurement of containing materials has been used widely. this paper has tried t...

Background and objectives: Non-alcoholic fatty liver disease (NAFLD) is a chronic liver disease caused by the accumulation of large amounts of fat in the hepatocytes. Given that atorvastatin is effective for treatment of NAFLD, the present study investigated effects of high-fat/fructose diet (HFFD) with atorvastatin on liver enzymes and lipid profile in a NAFLD rat model. Methods: Thirty-two m...

This paper develops a bias correction scheme for reparametrized inverse gamma regression models with varying precision [Bourguignon M, Gallardo DI. Reparametrized precision. Stat Neerl. 2020;74(4):611–627], which is tailored to situations where the response variable has an asymmetrical shape on positive real line. In particular, we discuss maximum-likelihood estimation model parameters and deri...
