Poissonsarja
Poissonsarja is a Finnish term that translates to "Poisson series" or "Poisson sequence." It generally refers to a series or sequence of events or observations that follow a Poisson distribution. A Poisson distribution is a discrete probability distribution that expresses the probability of a given number of events occurring in a fixed interval of time or space if these events occur with a known constant average rate and independently of the time since the last event.
In statistical analysis, a Poissonsarja would be used to model phenomena where events are rare but occur
The parameter associated with a Poisson distribution is lambda (λ), which represents the average rate of events
