I hope this article helped you to understand how the different versions of the Students t-test for two samples work and how to perform them by hand and in R. We can use it to make extremely skewed distributions less skewed especially for right-skewed distributions. 1 3 3 6 Box Cox Normality Plot Transform your data logarithmic or Box-Cox transformation among others or remove them be careful This concludes a relatively long article. . Logarithms are useful because they are interpretable. X i λ x i λ 1 λ if λ 0 ln x i if λ 0 x_ilambda begincases fracx_i. Changes in a log value are relative or percentage changes on the original scale. In this transformation were searching and evaluating all the other transformations and choosing the best one. Second one assumption of ST models is that all the variables involved in the study must be stationary. For example a logarithmic transformation is often useful. In this ...
