In statistics, kernel density estimation (KDE) is a non-parametric way to estimate the probability density function of a random variable.Kernel density estimation is a fundamental data smoothing problem where inferences about the population are made, based on a finite data sample.In some fields such as signal processing and econometrics it is also termed the Parzen–Rosenblatt window method.
