It is essentially a mixture of a discrete distribution (constant 0) and a continuous distribution (a truncated Gaussian distribution with interval $(0,\backslash infty)$). == Density function == The probability density function of a rectified Gaussian distribution, for which random variables ''X'' having this distribution are displayed as $X\; \backslash sim\; \backslash mathcal^)\backslash delta(x)+\; \backslash frac\}\backslash textrm(x).$ Here, $\backslash Phi(x)$ is the cumulative distribution function (cdf) of the standard normal distribution: : $$ \Phi(x) = \frac^x e^ \, dt \quad x\in\mathbb, $\backslash delta(x)$ is the Dirac delta function : and, $\backslash textrm(x)$ is the unit step function: : 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Rectified Gaussian distribution」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
