# commons-math-interpolation
This package is a partial TypeScript port of some Java classes of the [Apache Commons Math library](http://commons.apache.org/math).
The following forms of interpolation are implemented:
- [Akima cubic spline interpolation](https://en.wikipedia.org/wiki/Akima_spline)
- [Natural cubic spline interpolation](https://en.wikipedia.org/wiki/Spline_interpolation)
- [Linear interpolation](https://en.wikipedia.org/wiki/Linear_interpolation)
- [Nearest neighbor interpolation](https://en.wikipedia.org/wiki/Nearest-neighbor_interpolation)
The interpolators work on a dataset of x/y points (knots).
Additionally, a local regression algorithm is implemented that can be used in conjunction with the above interpolators.
- [LOESS/LOWESS local regression](https://en.wikipedia.org/wiki/Local_regression)
