Introduction: Colorectal cancer (CRC) is a commonly fatal cancer that ranks as third worldwide and third and the fifth in Iranian women and men, respectively. There are several methods for analyzing time to event data. Additive hazards regression models take priority over the popular Cox proportional hazards model if the absolute hazard (risk) change instead of hazard ratio is of primary concer...

OBJECTIVE Research on early life socioeconomic status (SES), education and mortality is less established in developing countries. This analysis aims to determine how SES and education are patterned across the life course and associated with adult mortality in Mexico. MATERIALS AND METHODS Data comes from 2001-2012 Mexican Health & Aging Study (Mexican adults age 50+, n= 11,222). Cox proportio...

Proportional hazard models for survival data, even though popular and numerically handy, suffer from the restrictive assumption that covariate effects are constant over survival time. A number of tests have been proposed to check this assumption. This paper contributes to this area by employing local estimates allowing to fit hazard models in which covariate effects are smoothly varying with ti...

PROBABILISTIC MODELS FOR MOTION SEGMENTATION IN IMAGE SEQUENCES

We consider recurrent event data when the duration or gap times between successive event occurrences are of intrinsic interest. Subject heterogeneity not attributed to observed covariates is usually handled by random effects which result in an exchangeable correlation structure for the gap times of a subject. Recently, efforts have been put into relaxing this restriction to allow non-exchangeab...

Despite growing interest from practitioners, politicians and the media, the political representation of Muslim ethnic minority women in the West has received scant scholarly attention. I address this gap with new data on the representation of Muslim ethnic minority women and men in 20 national legislatures from 2000 to 2010. Results reveal that Muslim ethnic minority women are increasingly elec...
