Bayesian Mixture Modelling with Ranked Set Samples
Amirhossein Alvandi, Sedigheh Omidvar, Armin Hatefi +3
We consider the Bayesian estimation of the parameters of a finite mixture model from independent order statistics arising from imperfect ranked set sampling designs. As a cost-effe…
Unsupervised Liu-type Shrinkage Estimators for Mixture of Regression Models
Elsayed Ghanem, Armin Hatefi, Hamid Usefi
In many applications (e.g., medical studies), the population of interest (e.g., disease status) comprises heterogeneous subpopulations. The mixture of probabilistic regression mode…
Multiple Observers Ranked Set Samples for Shrinkage Estimators
Andrew David Pearce, Armin Hatefi
Ranked set sampling (RSS) is used as a powerful data collection technique for situations where measuring the study variable requires a costly and/or tedious process while the sampl…
