The double f-class generalized ridge regression estimator is known to be a modified estimator of the generalized ridge regression estimator. In this paper, the exact distribution and density functions of the 'expanded'double f-class generalized ridge estimator are derived. Based on the density function derived, the performance of the relative efficiency of the expanded estimator to the ordinary least squared estimator is also evaluated by numerical analysis for two prior distributions
