Abstract
In present paper, some shrinkage testimators for the variance of a Normal distribution have been suggested under the invariant form of the LINEX loss function assuming initiate estimate of is available in the form of a point estimate . The comparisons of the proposed testimators have been made with the improved estimator under the squared error loss and the LINEX loss criteria.
