**location family**is a class of probability distributions that is parametrized by a scalar- or vector-valued parameter [math] x_0 [/math] , which determines the "location" or shift of the distribution. Formally, this means that the probability density functions or probability mass functions in this class have the form : [math] f_{x_0}(x) = f(x - x_0). [/math] Here, [math] x_0 [/math] is called the location parameter. Examples of location parameters include the mean, the median, and the mode.Thus in the one-dimensional case if [math] x_0 [/math] is increased, the probability density or mass function shifts rigidly to the right, maintaining its exact shape.

A location parameter can also be found in families having more than one parameter, such as location-scale families. In this case, the probability density function or probability mass function will be a special case of the more general form : [math] f_{x_0,\theta}(x) = f_\theta(x-x_0) [/math] where [math] x_0 [/math] is the location parameter,

*θ*represents additional parameters, and [math] f_\theta [/math] is a function parametrized on the additional parameters.
