... of branching rules r = U → W U in h − , and I(.) is an indicator func- tion taking on the value 1 when its argument is 676 true, and 0 otherwise. The n r term is derived by integrating over all ... of p $ , and not- ing that the total number of U productions in h − is n − + 1. Using these equations we can simply proceed through the data, sampling each potential bound- ary point in...
