Kernel Density Estimation and Non-Parametric Regression

The bandwidth of the kernel is a free parameter which exhibits a strong influence on the resulting estimate. To illustrate its effect, we take a simulated random sample from the standard normal distribution (plotted at the blue spikes in the rug plot on the horizontal axis). The grey curve is the true density (a normal density with mean 0 and variance 1). In comparison, the red curve is undersmoothed since it contains too many spurious data artifacts arising from using a bandwidt… WebGaussian Bandwidth scopes, which include Keysight’s Infiniivision scope family, with rated bandwidths less than 1GHz, are based on a simple equation which relates scope bandwidth to signal rise/fall time.
