Box Cox Method Python. In many statistical techniques we assume that the errors are normally distributed. The formula of transformation is defined as below.

Feb 26 2010 The statisticians George Box and David Cox developed a procedure to identify an appropriate exponent Lambda l to use to transform data into a normal shape The Lambda value indicates the power to which all data should be raised. After writing a simple script to perform the transformation my accuracy measures jumped to nearly 80 an incredible 20 increase.

This assumption allows us to construct confidence intervals.
Running the example transforms the dataset and plots histograms of each input variable. Sometimes a Box-Cox transformation provides a shift parameter to achieve this. With this operation we can generalize our model and pick one of the variations when necessary. Boxcox requires the input data to be positive.
