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 .The Box-Cox t (BCT) distribution is presented as a model for a dependent variable Y exhibiting both skewness and leptokurtosis. The distribution is defined by a power transformation Y v .The main objective in the analysis of Box-Cox transformation model is to make inference on the transformation parameter λ, and Box and Cox(1964) considered two approaches. The Box–Cox t (BCT) distribution is presented as a model for a dependent variable Y exhibiting both skewness and leptokurtosis. The distribution is defined by a power transformation Y ν having.

The Box-Cox transformation is a particulary useful family of transformations to convert a non-normal behaving data set into an approximately a normal distribution.A Box Cox transformation is a transformation of non-normal dependent variables into a normal shape. Normality is an important assumption for many statistical techniques; if your data isn’t normal, applying a Box-Cox means that you are .

Box-Cox transformation is a statistical technique that involves transforming your target variable so that your data follows a normal distribution. A target variable is the variable in your analytical model that you are trying to .The Box-Cox t (BCT) distribution is presented as a model for a dependent variable Y exhibiting both skewness and leptokurtosis. The distribution is defined by a power transformation Y ν .Using the Box–Cox power exponential distribution within the generalized additive models for location, scale and shape framework, we are able to model box-office revenues and develop probabilistic statements about revenues.

Box-Cox t distribution for fitting a GAMLSS Description. The function BCT() defines the Box-Cox t distribution, a four parameter distribution, for a gamlss.family object to be used in GAMLSS fitting using the function gamlss().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.

Extra distributions can be created, by transforming, any continuous distribution deﬁned on the real line, to a distribution deﬁned on ranges 0 to inﬁnity or 0 to 1, by using a ’log’ or a ’logit’ transformation respectively. BCT() returns a gamlss.family object which can be used to fit a Box Cox-t distribution in the gamlss() function. dBCT() gives the density, pBCT() gives the distribution function, qBCT() gives the quantile function, and rBCT() generates random deviates.

The distribution is defined by a power transformation Y ν.The Box-Cox t (BCT) distribution is presented as a model for a dependent variable Y exhibiting both skewness and leptokurtosis. The distribution is defined by a power transformation Y v having a shifted and scaled (truncated) t distribution with degrees of freedom parameter τ. The Box-Cox t Distribution Description. Density, distribution function, quantile function, and random generation for the Box-Cox t distribution with parameters mu, sigma, lambda, and nu. Usage

A Box Cox transformation is a transformation of non-normal dependent variables into a normal shape. Normality is an important assumption for many statistical techniques; if your data isn’t normal, applying a Box-Cox means that you are able to run a broader number of tests.The function BCT() defines the Box-Cox t distribution, a four parameter distribution, for a gamlss.family object to be used in GAMLSS fitting using the function gamlss() . The functions dBCT , pBCT , qBCT and rBCT define the density, distribution function, quantile function and random generation for the Box-Cox t distribution.
