An efficient single stage shrinkage estimator for the scale parameter of inverted gamma distribution

الملخص EN

The present paper agrees with estimation of scale parameter θ of the Inverted Gamma (IG) Distribution when the shape parameter α is known (α=1), bypreliminarytestsinglestage shrinkage estimators using suitable shrinkage weight factor and region.

The expressions for the Bias, Mean Squared Error [MSE] for the proposed estimators are derived.

Comparisons between the considered estimator with the usual estimator (MLE) and with the existing estimator are performed .The results are presented in attached tables.
