+The histogram is a simple and for a long time the most used non-parametric estimator.
+However, its inability to produce a continuous estimate dismisses it for many applications where a smooth distribution is assumed.
+In contrast, the KDE is often the preferred tool because of its ability to produce a continuous estimate and its flexibility.
+Given $n$ independently observed realizations of the observation set $X=(x_1,\dots,x_n)$, the kernel density estimate $\hat{f}_n$ of the density function $f$ of the underlying distribution is given with
+\begin{equation}
+\label{eq:kede}
+\hat{f}_n = \frac{1}{nh} \sum_{i=1}^{n} K \left(  \frac{x-X_i}{h} \right)  \text{,} %= \frac{1}{n} \sum_{i=1}^{n} K_h(x-x_i)
+\end{equation}
+where $K$ is the kernel function and $h\in\R^+$ is an arbitrary smoothing parameter called bandwidth.
+While any density function can be used as the kernel function $K$ (such that $\int K(u) \dop{u} = 1$), a variety of popular choices of the kernel function $K$ exits.
+Commonly the Gaussian kernel is used.
