Problem 5 Run the causal discovery program on some of the data sets at our book web site. Try the program with and without giving it prior information (such as variable order).

Evaluate how well it has done in one of two ways:

1. In terms of either predictive accuracy, KL distance or information reward (see Chapter 10).

2. By qualitative or quantitative comparison with an alternative causal discovery program (perhaps from one of the problems above, or also downloaded by you).
