Shrinkage testimation for the variance of a normal distribution under asymmetric loss function

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 \sigma^2 is available in the form of a point estimate \sigma^2_0.
The comparisons of the proposed testimators have been made with the improved
estimator under the squared error loss and the LINEX loss criteria.
