N is used for empirical estimate of variance (like the kernel smoothing method) or variance of sample mean. The above methods apply in two dimensions (left-right). This is the PNN using Parzen window classification version 2 with kernel smoothing of inputs. This is now surprisingly easy to do. Not enough to the smaller ones. Well yes there are several, but I think Kernel Density plots (KDP) are a more effective way to illustrate the distribution of a variable. Here you will file the standard PNN called version 2. A "smoothing kernel," an equation for evaluating noisy data, is often used in the process, but there's an art to choosing the right equation, and a different kernel can give very different results. Most recently it was problem #9 on ASM PE3 involving finding the variance of the kernel smoothed estimator. The setting is the same as in the Demonstration "Nonparametric Curve Estimation by Kernel Smoothers: Efficiency of Unbiased Risk Estimate and GCV Selectors". You need to have the PFE indicator. Kernel density estimation is a method to obtain smooth approximations of a distribution through nonparametric techniques.
