Key Concepts

Poisson Distribution

The Poisson distribution is used to model the number of times an event occurs in a fixed interval of time or space. It assumes that events occur independently and with a constant average rate, and its single parameter, lambda (?), represents both the mean and the variance of the distribution.

Cumulative Probability and Poisson CDF

Cumulative probability refers to the probability of having up to a certain number of events. In the context of the Poisson distribution, the cumulative distribution function (CDF) is used to calculate the probability of obtaining an outcome less than or equal to a specific value by summing up the probabilities of all outcomes up to that value.

Aggregation of Rates in Independent Intervals

When considering multiple independent intervals, the rate parameter (?) for the aggregated interval is the sum of the individual interval rates. This property allows for calculating probabilities over larger intervals by scaling the mean rate accordingly, while still using the Poisson model.
