I was thinking of censoring, maybe I should have said another word like floored.
The reason I think of this as censoring is that there are are some classical statistical models that model a distribution with a large mass at a minimum threshold, e.g. "tobit" censored regression.
Thanks for the explanation. I never paid much attention in my stats lectures so I deserve to have missed out on that term-of-art. I think the physics lingo would be to call it "capped" or "bounded" or "constrained".
