Abstract:
Some asymptotic expansions of quantiles of the $\Gamma$-distribution based on the Cornish–Fisher expansions are considered. The table of correction of the Wilson–Hilferty transformation is given. This table enables us to evaluate the quantiles of the $\Gamma$-distribution for all values of parameter $m\ge25$ and probabilities $0.0001\le p\le0.9999$ with the accuracy not less than six significant figures.
