In statistics, a unimodal probability distribution or unimodal distribution is a probability distribution which has a single peak. The term "mode" in this context refers to any peak of the distribution, not just to the strict definition of mode which is usual in statistics. If there is a single mode, the distribution function is called "unimodal". If it has … WebAs Henning Makholm points out, the result is not true in general.

No, unimodality of the margins doesn't imply unimodality of the joint -- it's quite possible to be unimodal on the margins and multimodal on the joint.
