A class of shrinkage estimators for the variance of a normal population

The crux of this paper is to propose a class of shrinkage estimators for the variance of a normal population and study its properties. Some estimators are generated from a proposed class and compared with the usual unbiased estimator, minimum mean squared error (MMSE) estimator and Pandey and Singh, South African Statistical Journal (1976) and J. Indian Statistical Assoc. 15, 141–150 (1977) estimator.
