在概率密度估计过程中,如果我们对随机变量的分布是已知的,那么可以直接使用参数估计的方法进行估计,如最大似然估计方法。 然而在实际情况中,随机变量的参数是未知的,因此需要进行非参数估计。核密度估计是非参数估计的一种方法,也就是大家经常听见的parzen 窗方法了。 本文主要介绍非参数估计的过程以及parzen窗方法估计...
在概率密度估计领域，当随机变量的参数未知时，我们使用非参数估计方法。其中，核密度估计是一种非参数估计方法，即著名的parzen 窗方法。本文将详细介绍非参数估计过程以及parzen窗方法在估计概率密度的原理与步骤。考虑未知概率密度函数$f(x)$，随机变量$x$落在区间$[a, b]$内的概率可通过下式表示：...
