Shape parameter

Kind of numerical parameter of a parametric family of probability distributions

In probability theory and statistics, a shape parameter is a kind of numerical parameter of a parametric family of probability distributions that is neither a location parameter nor a scale parameter. Such a parameter must affect the shape of a distribution rather than simply shifting it or stretching/shrinking it . For example, "peakedness" refers to how round the main peak is.
