可用

represents a half-normal distribution with parameter theta.

形式

HalfNormalDistribution[θ]

验证过的示例HalfNormalDistribution[1] → HalfNormalDistribution[1]Mean[HalfNormalDistribution[a]] → a^(-1)Variance[HalfNormalDistribution[a]] → (-2 + Pi)/(2*a^2)Median[HalfNormalDistribution[a]] → (Sqrt[Pi]*InverseErf[1/2])/a
