inverse gaussian距母函数 Inverse Gaussian分布,也称为逆高斯分布,是一种连续概率分布。它的概率密度函数(pdf)为: f(x) =√(π/ 2) * e^(-(x^2) / 2) * x 其中,x≥0。 逆高斯分布的累积分布函数(cdf)可以通过数值积分求解,但通常使用数值方法进行计算。 逆高斯分布的距离母函数(distance generating ...

It presents the variate relationships...
2.6 The normal inverse gaussian process Barndorff and Nielsen (1998) proposed the normal inverse Gaussian (NIG) distribution as a possible model for the stock price. This process may also be represented as a time-changed Brownian motion, where the time change T(t) is the first passage time ...

The inverse Gaussian distribution has the density function √λ2πx3exp{−λ2μ2x(x−μ)2} Background Also known as theWald distribution, the inverse Gaussian is used to model nonnegative positively skewed data. The distribution originated in the theory of Brownian motion, but has been used...

We introduce an alternative distribution to the gamma–gamma (GG) distribution, called inverse Gaussian gamma (IGG) distribution, which can efficiently describe moderate-to-strong irradiance fluctuations. The proposed stochastic model is based on a modulation process between small- and large-scale irradi...
