Detailed Description

template<typename Distance>
class theplu::yat::classifier::IGP< Distance >

Class for In Group Proportions (IGP)

IGP is defined to be the proportion of samples in a group whose nearest neighbours are also in the same group.

See also

Kapp and Tibshirani, Biostatistics (2006).

Distance should model concept Distance (but support for weighted iterators is not required).

Note

Distance must be symmetric, i.e., Distance(x,y) == Distance(y,x).
