Let's suppose we are attempting to predict traffic accidents on some highway. Traffic Accidents would be the response variable in our data set.
We have TWO competing models:
Two predictor variables: "Time of Day" and "Total Number of Cars Passing Particular Point Per Minute"
Two predictor variables: "Precipitation Level (Weather)" and "Number of Cars in FAST LANE Passing Particular Point Per Minute"
The goal is to select which of these two models appears to do a better job of predicting traffic accidents.
Additionally, we want to ascertain based on these two models, under what circumstances Traffic Accidents are highest and lowest. For instance, in model 1), what time of day, and what total car count per minute.
Question: Which statistical software package would you use? What specific procedure would you use? Why?
(Note: SAS and many other packages are available to use in our offices. SAS is preferred.)
