Types Metrics
TypeRank values are computed by applying the Google PageRank algorithm on the graph of types' dependencies. A homothety of center 0.15 is applied to make it so that the average of TypeRank is 1.
Types with high TypeRank should be more carefully tested because bugs in such types will likely be more catastrophic. It is a value calculated only by XDepend
