Poisson Cdf
Description
‡ (
Distr) Æ E:Poisson Cdf
Poisson Cdf
computes a cumulative probability for the discrete Poisson distribution with
the specified mean (
l).
Inputs
l A Poisson process mean; must be a real number > 0
Lower Value A lower scalar or list of values at which to evaluate the Poisson
distribution cdf. The default is Lˆ.
Upper Value An upper scalar or list of values at which to evaluate the Poisson
distribution cdf. The default is ˆ.
Outputs
Cdf A Poisson cdf value or list of values. Values are stored to cdf.
l A Poisson process mean.
LowVal A scalar lower value or list of values.
UpVal A scalar upper value or list of values.
Output statistic variables are stored in the STATVARS folder.
