By Dey D. K., Kuo L., Sahu S. K.

This paper describes a Bayesian method of blend modelling and a style in accordance with predictive distribution to figure out the variety of parts within the combos. The implementation is completed by using the Gibbs sampler. the tactic is defined in the course of the combos of standard and gamma distributions. research is gifted in a single simulated and one actual facts instance. The Bayesian effects are then in comparison with the possibility technique for the 2 examples.
