double & Bound()
Modify the bound.

void serialize(Archive &ar, const unsigned int)
Serialize the statistic.
Extra data for each node in the tree.
The core includes that mlpack expects; standard C++ includes and Armadillo.
RAQueryStat()
Initialize the statistic with the worst possible distance according to our sorting policy...
size_t & NumSamplesMade()
Modify the number of samples made.
size_t NumSamplesMade() const
Get the number of samples made.
double Bound() const
Get the bound.
RAQueryStat(const TreeType &)
Initialization for a node.
