AbstractFrailty models are used in the survival analysis to account for the unobserved heterogeneity in individual risks to disease and death. To analyze the bivariate data on related survival time...

AbstractThis paper studies asymptotic properties of the estimators of the regression coefficients in segmented line regression, focusing on the multi-phase regression model with the continuity cons...

AbstractIn risk theory, ruin probabilities and dividend strategies have drawn lots of attentions. The dual risk model assumes that the surplus process decreases at a constant rate over time and gai...

AbstractIn this short note, we give the representation of the non symmetric Rosenblatt process as a Wiener–Ito multiple integral with respect to the Brownian motion on a finite interval. Based on t...

AbstractThe paper deals with non parametric estimation of the joint distribution function of two random variables X and Y. Especially, we consider the case when one of the two variables, says Y, is...

Sample size estimation for comparing rates of change in K-group repeated binary measurements studies

AbstractIn clinical research, longitudinal trials are frequently conducted to evaluate the treatment effect by comparing trends in repeated measurements among different intervention groups. For suc...

AbstractThe most common Bayesian approach for detecting outliers is to assume that outliers are observations which have been generated by contaminating models. An alternative idea was applied by Ze...

Gaussian copula joint models to analysis mixed correlated longitudinal count and continuous responses

AbstractGaussian Copula joint models for analyzing mixed correlated longitudinal continuous and count responses with random effects are presented where the count response is defined by a latent var...

AbstractA procedure is proposed here for jointly visualizing the compatibility of a sample with a family of Skewed Exponential Power Distributions, of which the distributions known as Normal, Expon...

AbstractIn this work, we study semiparametric copula models under bivariate censoring. Basing on divergences theory, we propose new estimates for the parameter of the considered model and we establ...
