Consider a dataset on forest fires. An MLR analysis was done between temp, wind and rh using the code below: proc glm data = ; model temp = wind rh wind*rh; run; What is the purpose of the 'wind*rh' term in the model?
1) To include the interaction effect between wind and rh in the model
2) To exclude the interaction effect between wind and rh from the model
3) To include the main effect of wind and rh in the model
4) To exclude the main effect of wind and rh from the model
