Class deviation

boost::histogram::utility::deviation — Confidence level in units of deviations for intervals.


// In header: <boost/histogram/utility/binomial_proportion_interval.hpp>

class deviation {
  // construct/copy/destruct
  explicit deviation(double);

  // public member functions
  template<typename T> explicit operator T() const noexcept;
  operator confidence_level() const noexcept;


Intervals become wider as the deviation value increases. The standard deviation corresponds to a value of 1 and corresponds to 68.3 % confidence level. The conversion between confidence level and deviations is based on a two-sided interval on the normal distribution.
