Cox box python
Web3 Suppose I apply a Box-Cox transformation to my data and now it looks rather like a normal distribution. I then add another dataset, transform it by Box-Cox with the same lambda and run a t-test to compare the means. Would this approach make sense if my data is non-normal by its nature? Webscipy.special.inv_boxcox(y, lmbda, out=None) = # Compute the inverse of the Box-Cox transformation. Find x such that: y = (x**lmbda - 1) / lmbda if …

Box-Cox transform is an effective method (compared to previously discussed methods) to transform a variable’ distribution to look more like Gaussian. A drawback of this method is, it requires the values of a variable to be greater than 0. However, scaling the values to be positive can be done to use this …
