poisstat (Statistics Toolbox)

Mean and variance for the Poisson distribution.

Syntax

M = poisstat(LAMBDA)
[M,V] = poisstat(LAMBDA)

Description

M = poisstat(LAMBDA) returns the mean of the Poisson distribution with parameter, LAMBDA. M and LAMBDA match each other in size.

[M,V] = poisstat(LAMBDA) also returns the variance of the Poisson
distribution.

For the Poisson distribution:

Examples

Find the mean and variance for the Poisson distribution with

= 2:

[m,v] = poisstat([1 2; 3 4])

m =

     1     2
     3     4

v =

     1     2
     3     4
