The poisson calculator makes it easy to compute individual and cumulative poisson probabilities. It is also known, especially among physicists, as the lorentz distribution after hendrik lorentz, cauchylorentz distribution, lorentzian function, or breitwigner distribution. And this is really interesting because a lot of times people give you the formula for the poisson distribution and you can kind of just plug in the numbers and use it. This program will also compute the confidence interval for the yintercept as well as the slope of the line whereas the ti 84 program only does the slope.

Logistic regression is used when the dependent variable target is categorical. Normal distributions are used in the natural and social sciences to represent realvalued random variables whose distributions are not known. This command is used to calculate poisson distribution probability. Statfun83 provides each function as both a basic program and as an app. The simplest case of a gaussian distribution is known as the standard normal probability distribution.
