Poisson Distribution CDF and Quantile Calculator

An implementation of the Poisson Distribution CDF and Quantile function Calculator occurs below. The Poisson Distribution is a Probability Mass Function as it describes the distribution of discrete random variables, which are integers from 0 upwards i.e. positive integers. For parameter $\lambda$ (a real number greater greater than 0) the Poisson distribution function is:-


$\Large \frac{\lambda^k}{k!}e^{-\lambda}$  


where integer $k\geq 0$. The $\lambda$ field needs to be filled in, as well as one out of the two fields which are labelled Upper Limit and Probability. The upper limit field needs to contain an integer number greater than or equal to 0. The probability field must contain a number between 0 and 1 only.



$\lambda$:


Upper limit:

  1. I was diagnosed with COPD four years ago and struggled with worsening symptoms despite using inhalers and medications. Last year, I tried a herbal treatment from NaturePath Herbal Clinic, and to my surprise, it made a huge difference. My breathing improved, the coughing eased, and my energy came back. I feel better than I have in years. If you're dealing with COPD, I highly recommend checking them out: www.naturepathherbalclinic.com.
