Exemplos de Skewness em C++ (Cpp)

Exemplo n.º 1

Arquivo: NakagamiRand.cpp Projeto: StochasticEngineer/RandLib

double ChiRand::ExcessKurtosis() const
{
    double mu = Mean();
    double sigmaSq = Variance();
    double sigma = std::sqrt(sigmaSq);
    double skew = Skewness();
    double kurt = 1.0 - mu * sigma * skew;
    kurt /= sigmaSq;
    --kurt;
    return 2 * kurt;
}

Exemplo n.º 2

Arquivo: UnivariateDistribution.cpp Projeto: StochasticEngineer/RandLib

double UnivariateDistribution<T>::ThirdMoment() const
{
    double mean = Mean();
    double variance = Variance();
    double skewness = Skewness();

    double moment = skewness * std::sqrt(variance) * variance;
    moment += mean * mean * mean;
    moment += 3 * mean * variance;
    return moment;
}
