Signature Description Parameters
templat<typename T, typename I = unsigned long, typename = typename std::enable_if<std::is_arithmetic<T>::value, T>::type>
struct QuantileVisitor;
This is a “single action visitor”, meaning it is passed the whole data vector in one call and you must use the single_action_visit() interface.
This functor class finds the quantile specified by quantile and q_policy. Please see quantile_policy for more explanation.
explicit QuantileVisitor (value_type quantile, quantile_policy q_policy);
T: Column data type.
I: Index type.
