In our first paper on stochastic stability [1] we proved several results which we could not find in the literature. Professor Hasminskh* has kindly pointed out that several of our initial results can be obtained directly from theorems found in his book [2]. In particular, the results of §§1 and 2 of [1] follow directly from results in Chapters 5 and 6 of [2]. Furthermore, the methods of §6.8 of...

In some experiments this test provides additional and useful information to decide if methods are different.
