Member Data Documentation

m_valueIfNAN

const float m_valueIfNAN = -1.0

private

Define a default value to use if a variable cannot be calculated.

A value different from NAN, but which is not obtainable otherwise, can be useful if one wants the MVA classifier to train on the variable not being available instead of ignoring it.
