WebThe goodness-of-fit is determined by comparing two models statistically. For that reason, we will discuss the details of the procedure and the underlying rationale in Chapter 9, … WebLet’s dive into the output. We’ll start with the Goodness of Fit Test table below. The very first line shows our data are definitely not normally distributed, because the p-value for Normal is less than 0.005! We'll skip the two transformations (Box-Cox and Johnson) because we want to identify the native distribution rather than transform it.
