A standard approach to the analysis of skewed response data with concomitant information is to use a log-transformation to normalize the distribution of the response variable and then conduct a log- regression analysis. However, the mean response at original scale is often of interest....

This research was motivated by a desire to model the progression of a chronic disease through various disease stages when data are not available to directly estimate all the transition parameters in the model. This is a common occurrence when time and expense make it infeasible to follow a...

Abstract Empirical research with Markov regime-switching models often requires the researcher not only to estimate the model but also to test for the presence of more than one regime. Despite the need for both estimation and testing, methods of estimation are better understood than are methods...

Purpose – The purpose of this paper is to apply a numerical simulation of stochastic processes to the problem of real estate investment appraisal. Design/methodology/approach – These uncertain operating costs are integrated into an enhanced dynamic simulation. To model the dynamics in the...

Recent studies suggest that payoffs in cents, compared to dollars, produce less defection in a repeated prisoner’s dilemma game. We are unable to replicate these findings with conventional economic procedures or in a direct replication.

Often in biomedical studies, the event of interest is recurrent and within-subject events cannot usually be assumed independent. In semi-parametric estimation of the proportional rates model, a working independence assumption leads to an estimating equation for the regression parameter vector,...

In biomedical studies, the event of interest is often recurrent and within-subject events cannot usually be assumed independent. In addition, individuals within a cluster might not be independent; for example, in multi-center or familial studies, subjects from the same center or family might be...
