Model comparison using AICs in a stepwise backward selection approach. Coefficients are the results of modelling with scaled variables. Model 1 was built with no interaction terms. Models 2–6 included interaction terms and insignificant variables were removed one by one in a backward selection approach. Model 6 was considered the best model because it yielded the lowest AIC.
