## Usage

### Prerequisite

The kernel density estimates are computed with fast Fourier transforms (FFTs) internally using the [AbstractFFTs.jl](https://github.com/JuliaMath/AbstractFFTs.jl) interface.
You have to load a backend such as [FFTW.jl](https://github.com/JuliaMath/FFTW.jl) that implements this interface:

```julia
using FFTW
```

### Univariate
The main accessor function is `kde`:
