The aim of this paper is to provide a composite likelihood approach to handle spatially correlated survival data using pairwise joint distributions. With e-commerce data, a recent question of interest in marketing research has been to describe spatially clustered purchasing behavior and to...

During the last decade Levy processes with jumps have received increasing popularity for modelling market behaviour for both derviative pricing and risk management purposes. Chan et al. (2009) introduced the use of empirical likelihood methods to estimate the parameters of various diffusion...

Empirical likelihood (EL) ratio tests are developed for testing for or against the hypothesis that k-population means [mu]1,[mu]2,...,[mu]k are isotonic with respect to some quasi-order [not precedes, equals] on {1,2,...,k}. The null asymptotic distributions are derived and are shown to be of...

We propose a unified estimation method for semiparametric linear transformation models under general biased sampling schemes. The new estimator is obtained from a set of counting process-based unbiased estimating equations, developed through introducing a general weighting scheme that offsets...
