Comparison of information criteria scores computed using the T₅₀ and T₉₀ durations for the ‘KW trig’ and ‘KW & BAT’ samples. The following designations are introduced for the models: 𝒩 (𝒮𝒩) and 𝒯 (𝒮𝒯) denote the symmetric (skewed) Gaussian and Student distributions, correspondingly; the number to the left of the model provides the amount of clusters; and the number in parentheses gives the amount of free parameters of the model. The red filled area corresponds to the Δ_IC < 2 area, while the blue filled area marks the 2 < Δ_IC < 4 area.
