Function File: [m, v] = poisstat (lambda)

Compute mean and variance of the Poisson distribution.

Arguments

• lambda is the parameter of the Poisson distribution. The elements of lambda must be positive

Return values

• m is the mean of the Poisson distribution
• v is the variance of the Poisson distribution

Example

          lambda = 1 ./ (1:6);
          [m, v] = poisstat (lambda)
