What is poisson distibution explain the chacterstics amd formula of poisson distribution?
Answers
Poisson distributions are used to calculate the probability of an event occurring over a certain interval. The interval can be one of time, area, volume or distance. You can find the probability of an event occurring is found using the formula in the Poisson distribution formula image.
The Poisson distribution describes rates. It is a very simple distribution with a single parameter. You can think of a parameter as a value that you plug in as a “setting” to configure a little object that you can draw random values from.
CHARACTERISTICS:
The parameter for the Poisson distribution is conventionally (usually) represented with the Greek lambda symbol. It represents the expected rate, where the rate isn’t necessarily in time—-It could be any “something” per “something else,” where the denominator is some fixed interval in a continuous dimension. Like change in pressure per degree change in temperature.
FORMULA:
P(x; μ) = (e-μ * μx) / x!
