In this paper, we study Bayesian asymptotic properties of the proportional hazards model where link function is modeled by generalized additive model. As standard is, a useful tool in finding nonlinearity covariate effects to survival times. We develop data-dependent sieve prior for and use bootstrap baseline hazard function. prove that posterior contraction rate minimax optimal up logn term wh...
This paper studies Cox‘s proportional hazards model under covariate measurement error. Nakamura‘s (1990) methodology of corrected log-likelihood will be applied to the so called Breslow likelihood, which is, in the absence of measurement error, equivalent to partial likelihood. For a general error model with possibly heteroscedastic and non-normal additive measurement error, corrected estimator...
When there are covariate effects to be considered, multistate survival analysis is dominated either by parametric Markov regression models or by semiparametric Markov regression models using Cox’s (1972) proportional hazards models for transition intensities between the states. The purpose of this research work is to study alternatives to Cox’s model in a general finite-state Markov process set...
The primary objective of this work was to investigate and compare the use of the Cox proportional hazards model and Aalen’s additive model in analysing survival data. Survival data from a study of 52 patients with advanced breast cancer was investigated using the Cox proportional hazards model. The model was optimized by examining different aspects by use of appropriate residual plots. Covariat...
study of cohesive devices in the textbook of english for the students of apsychology by rastegarpour
this study investigates the cohesive devices used in the textbook of english for the students of psychology. the research questions and hypotheses in the present study are based on what frequency and distribution of grammatical and lexical cohesive devices are. then, to answer the questions all grammatical and lexical cohesive devices in reading comprehension passages from 6 units of 21units th...
The additive hazard regression model plays an important role when the excess risk is quantity of interest compared to relative risks, where proportional better. This paper discusses parametric analysis survival data using hazards with competing risks in presence independent right censoring. In this paper, baseline function parameterized a modified Weibull distribution as lifetime model. paramet...
