# Physics307L F09:People/Mondragon/Poisson

The desire to perform these experiments arose from arguments about how accurately a Poisson probability distribution could fit data that should most probably follow the Poisson distribution. One thing I see immediately is that the Poisson distribution can not fit data collected from a finite number of counting experiments **exactly** but as the number of counting experiments preformed approaches infinity, the data should fit the distribution more and more tightly.

I will be using the **poissrnd()** function included in Gnu Octave vers. 3.0.0 to generate random numbers with a Poisson distribution with parameter **Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://api.formulasearchengine.com/v1/":): {\displaystyle \lambda}**
. Gnu Octave is open source, so it shouldn't be too difficult to find the source code and examine how these numbers are generated for those who are curious. I am using this number generator to model counting experiments.

Things I want to do:

- using the Poisson random number generator, generate
