Bayesian estimation of shift point in poisson model under asymmetric loss functions

The paper deals with estimating shift point which occurs in any sequence of independent observations x 1,.......,x m,x m+1,.... x n of poisson model in statistical process control. this shift point occurs in the sequence when i.e. m life data are observed. the bayes estimator on shift point 'm' and before and after shift process means λ 1 & λ 2 are derived for symmetric and asymmetric loss functions under informative and non informative priors. the sensitivity analysis of bayes estimators are carried out by simulation and numerical comparisons with r-programming. the results show the effectiveness of shift in sequence of poisson distribution.
