Program to fit to Poisson distributed data.

Uses actual Poisson probability (i.e. not Gaussians, and therefore not least squares).

Installation

Download using:
git clone https://www.av8n.com/cgit/poissfit

The fitting program requires the libnlopt-cxx-dev package. The SVD program requires libarmadillo-dev package. Both of those are easily installable on Ubuntu and similar platforms.

In the poissfit directory, compile using a simple make command. That works on my Ubuntu platform. Other platforms are likely to work; the code uses fairly basic language features (c++11 or later).

Some data files, suitable for input to the program, can be found here.
