Box–Cox distribution : ウィキペディア英語版 | Box–Cox distribution 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 : for ''y'' > 0, where ''m'' is the location parameter of the distribution, ''s'' is the dispersion, ''ƒ'' is the family parameter, ''I'' is the indicator function, Φ is the cumulative distribution function of the standard normal distribution, and sgn is the sign function. ==Special cases==
* ''ƒ'' = 1 gives a truncated normal distribution.
