Multivariant or Multivariate?

When testing performance or the output of different combinations of elements against one another - is it correct to say it's a "multivariant" test? Or is it a "multivariate" test?


This is really a technical question rather than an English question, but the answer is it's 'Multivariate": "involving a number of distinct, though not usually independent, random variables"


I've only heard of "multivariate analysis" in statistics. When I try to search for "define multivariant," Bing corrects the word and says it's "Including results for define multivariate."
