Diagnostic worm plots for assessing the fitness of models using the generalized beta type 1 (GB1) distribution (a), Skew t‐distribution type 2 (ST2) (b), Beta (BE) distribution (c), and Normal (NO) distribution (d) to the FAS variable. A good fit is represented by ≈ 95% of values lying between the two green dotted elliptic lines and close to the deviation value of 0.0. In this example, the GB1 and ST2 distributions fit well most of the data but they struggle to fit the values in the tails of the FAS variable (although the ST2 distribution models better the right tail of the data than the GB1 distribution). However, compared to the GB1 and ST2 models, BE and NO exhibit a poor fit overall.
