In statistics, the Box–Cox distribution (also known as the power-normal distribution) is the distribution of a random variable X for which the Box–Cox transformation on X follows a truncated normal distribution. It is a continuous probability distribution having probability density function (pdf) given by
In statistics, a power transform is a family of functions applied to create a monotonic transformation of data using power functions.It is a data transformation technique used to stabilize variance, make the data more normal distribution-like, improve the validity of measures of association (such as the Pearson correlation between variables), and for other data stabilization procedures.
The parameter q represents the degree of non-extensivity of the distribution. ... proposed by George Box and David Cox in 1964. [2] q-exponential
He offered the following critique of Wikipedia’s article on the Box-Cox distribution: Wikipedia defines the Box-Cox distribution as “the distribution of a random variable X for which the Box–Cox transformation on X follows a truncated normal distribution.” The truncated-normal variate is defined as Y, which is the Box-Cox transformation ...
The exponential distribution is recovered as . Originally proposed by the statisticians George Box and David Cox in 1964, [2] and known as the reverse Box–Cox transformation for =, a particular case of power transform in statistics.

The first two population distribution parameters and are usually characterized as location and scale parameters, while the remaining parameter(s), if any, are characterized as shape parameters, e.g. skewness and kurtosis parameters, although the model may be applied more generally to the parameters of any population distribution with up to four ...
