Partisan Differential=Registration advantage as a percentage between the two parties. For example, if 35% of the Registered voters are Republican and 30% are Democrat than the Partisan Differential will be R +5.
Any time the model spits out a probability either equal to or above 100% we call the race "Safe" and any probability between 59% and 50% is a "TOSS UP".
This model is woefully incomplete right now. It only uses two variables (PDiff and a bivariate code for who won) and it only uses data from 2004. Version two will be out within a fortnight and it will include 2002 data plus other variables if they are statistically significant.
