Detailed Description

template<typename T = double>
class FreqTable< T >

Frequency table of vectors.

This is mostly used in Support. The main data is contained in the data double vector. The matrix is stored in a row-wise fashion, where the first element is the frequency with which the vector is observed.

For example, in a model with k terms the first k + 1 elements of data would be:

  • weights
  • term 1
  • term 2
  • ...
  • term k
