boxcox transforms nonnormally distributed data to a set of data that has approximately normal distribution.

The Box-Cox transformation transforms our data so that it closely resembles a normal distribution. In many statistical techniques, we assume that the errors are normally distributed. This assumption allows us to construct confidence intervals and conduct hypothesis tests. Box Cox transformation was first developed by two British statisticians namely George Box and Sir David Cox. When the assumption of data normally distributed is violated or the relationship between the dependent and independent variables in case of linear model are not linear, in such situations some transformations methods that may help the data set follow a normal distribution. The Box-Cox Transformations procedure is designed to determine an optimal transformation for Y while fitting a linear regression model. It is useful when the variability of Y changes as a function of X. Often, an appropriate transformation of Y both stabilizes the variance and makes the deviations around the model more normally distributed. However, an appropriatetransformation of a data set can often yield a data set that doesfollow approximately a normal distribution.
