TIME-DEPENDENT RANDOM EFFECT POISSON RANDOM FIELD MODEL FOR POLYMORPHISM WITHIN AND BETWEEN TWO RELATED SPECIES by Shilei Zhou Dr. Amei Amei, Examination Committee Chair Associate Professor of Mathematical Sciences University of Nevada Las Vegas Molecular evolution is partially driven by mutation, selection, random genetic drift, or combination of the three factors. To quantify the magnitude of...

The article focuses on mortality models with a random effect applied in order to evaluate human more precisely. Such are called frailty or Cox models. main assertion of the paper shows that each positive transforms initial hazard rate (or density function) new absolutely continuous survival function. In particular, well-known Weibull and Gompertz rates corresponding functions analyzed different...

We investigate the mechanism that leads to systematic deviations in cluster Monte Carlo simulations when correlated pseudo-random numbers are used. We present a simple model, which enables an analysis of the effects due to correlations in several types of pseudo-random-number sequences. This model provides qualitative understanding of the bias mechanism in a class of cluster Monte Carlo algorit...

Research synthesis plays a central role in the process of scientific discovery, providing a formal methodology for the systematic accumulation and evaluation of scientific evidence. There are many situations in which research synthesis is required because obtaining the required information from an individual trial is not possible or practical. This thesis proposes a general method to synthesize...
