[R] Predict function

2012-02-02 Thread Davg
I've created a linear model and am trying to use the predict function to predict the outcome of a sports game. I have four explanatory variables a,b,c,d. where a,b relate to the home team and c,d relate to the away team. i'd like to know the probability that the home team wins (assuming no draw
