Following Long ( 2012 ), we then interpreted the chosen model by looking at the coefficients together with visually inspecting the plot of the fitted model. As shown in the table, the simplest model that provided a marginally significant better fit of the data than simpler models was the cubic model, χ 2 (7) = 12.9371 , p = 0.07365.
