WebThe number of times an event occurs (the observation) R’s rpois function generates Poisson random variable values from the Poisson distribution and returns the results. The function takes two arguments: Number of observations you want to see. The estimated rate of events for the distribution; this is expressed as average events per period. WebThe Poisson distribution is the probability distribution of independent event occurrences in an interval. If λ is the mean occurrence per interval, then the probability of having x …
