Default Re: calculation 4.8 on p.139

Not a problem. The two constructions generate identically distributed Dtrain and Dval.

The partitioning approach in construction 1 generates data points with disjoint indices. That does not mean that the data points in Dtrain cannot also appear in Dval. (remember that when you generate D, the data points are iid so there can be repetitions.)
