scicpp::stats::mean, nanmean, tmean¶

Defined in header <scicpp/core.hpp>

Compute the arithmetic mean.

template<class Array, class Predicate>
constexpr auto mean(const Array &f, Predicate filter)¶

Compute the arithmetic mean of an array using only the values satisfying the filter predicate.

template<class Array>
constexpr auto mean(const Array &f)¶

Compute the arithmetic mean of an array.

template<class Array>
auto nanmean(const Array &f)¶

Compute the arithmetic mean of an array, ignoring NaNs.

template<class Array>
constexpr auto tmean(const Array &f, const std::array<T, 2> &limits, const std::array<bool, 2> &inclusive)¶

Compute the arithmetic mean of an array, ignoring values outside the given limits. Use the optional parameter inclusive to specify whether the limits are included (by default they are included).

#include <scicpp/core.hpp>
#include <cstdio>

int main()
{
    const std::array a{-1., 1., 2., 3.};

    // Compute the mean of the array
    auto m = scicpp::stats::mean(a);

    // Compute the mean of the positive values of the array
    auto m_pos = scicpp::stats::mean(a, [](auto x) { return x >= 0; });

    printf("m = %f, m_pos = %f\n", m, m_pos);
}
