eli5: What is multimodal distribution? With examples, please 🙂
In: 18
A multimodal distribution is a continuous probability distribution with two or more modes. Like two or more local maxima in the probability density function. Modes are points in the distribution where the probability density is highest, and a distribution can have more than one mode if it has more than one peak.
It can be bimodal distributions, which are often used to describe data sets that have two distinct groups or clusters, such as the heights of men and women in a population. There is trimodal… Etc.
There more mode the more diffucult, there are specialized statistical techniques and tools available for analyzing multimodal data, such as nonparametric density estimation methods and mixture models but it’s not Eli5 anymore (mmmh it’s never been I think).
