高斯函數積分列表

為標準正態概率密度函數，

${\displaystyle \Phi (x)=\int _{-\infty }^{x}\phi (t)\,dt={\frac {1}{2}}\left(1+\operatorname {erf} \left({\frac {x}{\sqrt {2}}}\right)\right)}$

在這些表達式中，

${\displaystyle \phi (x)={\frac {1}{\sqrt {2\pi }}}e^{-{\frac {1}{2}}x^{2}}}$

為對應的累積分布函數，其中erf為誤差函數，

${\displaystyle T(h,a)=\phi (h)\int _{0}^{a}{\frac {\phi (hx)}{1+x^{2}}}\,dx}$

為歐文T函數（英語：Owen's T function）。

不定積分

${\displaystyle \int \phi (x)\,dx=\Phi (x)+C}$

${\displaystyle \int x\phi (x)\,dx=-\phi (x)+C}$

${\displaystyle \int x^{2}\phi (x)\,dx=\Phi (x)-x\phi (x)+C}$

${\displaystyle \int x^{2k+1}\phi (x)\,dx=-\phi (x)\sum _{j=0}^{k}{\frac {(2k)!!}{(2j)!!}}x^{2j}+C}$

在這些積分中，n!!為雙階乘：若n為偶數，則等於從2到n的所有偶數的乘積；若n為奇數，則等於從1到n的所有奇數的乘積；特別地，0!! = (−1)!! = 1。

${\displaystyle \int x\phi (x)\Phi (a+bx)\,dx={\frac {b}{t}}\phi \left({\frac {a}{t}}\right)\Phi \left(xt+{\frac {ab}{t}}\right)-\phi (x)\Phi (a+bx)+C,\qquad t={\sqrt {1+b^{2}}}}$

${\displaystyle \int \Phi (x)^{2}\,dx=x\Phi (x)^{2}+2\Phi (x)\phi (x)-{\frac {1}{\sqrt {\pi }}}\Phi \left(x{\sqrt {2}}\right)+C}$

${\displaystyle \int e^{cx}\phi (bx)^{n}\,dx={\frac {e^{\frac {c^{2}}{2nb^{2}}}}{b{\sqrt {n(2\pi )^{n-1}}}}}\Phi \left({\frac {b^{2}xn-c}{b{\sqrt {n}}}}\right)+C,\qquad b\neq 0,n>0}$
