English to German Medical Mathematics & Statistics Statistical analysis of clinical study results

I am translating the statistics section of a clinical study protocol and came across the description, "The type I error will be controlled by flexible alpha splitting and alpha recycling."

Alpha splitting is a mathematical procedure for correcting the type I error (alpha) for multiple testing, in order to avoid false positives by simply testing often enough to get a significant result by chance. There are not too many, but quite solid references for the English term as this seems to be a recent statistical development. My problem is that I find neither evidence for the English term being used in German (as is often the case with statistics) nor evidence for some equivalent German term.
(NB: During my search, I also came across the alternative method of alpha exhaustive multiple testing. I don't need this one for my current text, but would be interested to learn about the German translation of "alpha exhaustive" out of curiosity and for further reference.)

TIA for your help!
