Conclusion
The modification of the three-parameter gamma distribution obtained is more flexible and more adequately descrit right tail of the empirical probability distribution. The proposed probabilistic model is more statistically stable (robu ative to the initial (input) information, since it satisfies the invariance property: the parameters of the new distributive are invariant.
The analytically substantiated modification of the three-parameter gamma distribution is invariantly robust.
