精选优质文档-倾情为你奉上正态分布的概率密度函数的推导An interesting question was posed in a Statistics assignment which was to show that the standard normal distribution was valid - ie the integral from negative infinity to infinity equated to one and in doing so showed the derivation of the part of the normal pdf.A friend of mine and I decided to try to derive the normal pdf and the thinking went along the lines of the central limit theorem which states that the mean of any probability distribution becomes n
