Modeling Count Data from Dependent Clusters with Poisson Mixed Models

K. A. N. K. Karunarathna & Pushpakanthie Wijekoon · Asian Journal of Probability and Statistics · 2018

Responses collected from dependent clusters are affected by the dependence among clusters and it should be taken into account in modeling such responses. In this study, a new approach was evaluated to incorporate cluster dependence in generalized linear Poisson mixed models for c...

Preliminary Test Stochastic Restricted r-k Class Estimator and Preliminary Test Stochastic Restricted r-d Class Estimator in Linear Regression Model

Sivarajah Arumairajan & Pushpakanthie Wijekoon · Journal of Advances in Mathematics and Computer Science · 2014

In this study two new preliminary test stochastic restricted estimators, a Preliminary Test stochastic restricted r-k class estimator and a Preliminary Test stochastic restricted r-d class estimator, are proposed. The comparison of one estimator over the other is done in the mean...
