- Poisson( <Mean> )
- Returns a bar graph of a Poisson distribution with given mean λ.
- Poisson( <Mean>, <Boolean Cumulative> )
- Returns a bar graph of a Poisson distribution when Cumulative = false.
- Returns a graph of a cumulative Poisson distribution when Cumulative = true.
- The first parameter is same as above.
- Poisson( <Mean>, <Variable Value v>, <Boolean Cumulative> )
- Let X be a Poisson random variable.
- Returns P( X = v) when Cumulative = false.
- Returns P( X ≤ v) when Cumulative = true.
- First parameter is same as above.
- Examples:
Poisson(3, 1, true)
yields 0.2 in the Algebra View and \frac{4}{e³} in the CAS View.Poisson(3, 1, false)
yields 0.15 in the Algebra View and \frac{3}{e³} in the CAS View.
- Note: A simplified syntax is available to calculate P(u ≤ X ≤ v): e.g.
Poisson(1, 1..5)
yields 0.63153, that is the same as Poisson(1, {1, 2, 3, 4, 5}).
