A model for counting occurrences over a fixed interval, relying on a mean rate and suitable for rare events. Binomial Distribution
A model for counting successes in a fixed number of trials, each with the same probability of success. Occurrence
An event counted within a fixed interval, such as birds landing or cars passing, central to Poisson modeling. Interval
A fixed span, often time or space, over which events are counted in Poisson experiments. Mean Rate
The average number of events expected per interval, represented by lambda in Poisson contexts. Lambda
A parameter indicating the mean rate of events per interval, used in Poisson probability calculations. Variance
A measure of spread in Poisson distribution, always equal to the mean rate parameter. Standard Deviation
A measure of variability in Poisson distribution, calculated as the square root of the mean rate. Probability Distribution Function
A formula assigning probabilities to each possible count of occurrences in Poisson distribution. Poisson PDF
A calculator function for finding the probability of exactly a specific number of occurrences. Poisson CDF
A calculator function for finding the probability of at most a certain number of occurrences. Independence
A condition where events in different intervals do not affect each other, required for Poisson modeling. Estimation
The process of using Poisson formulas to approximate binomial probabilities when trials are numerous and success is rare. Factorial
A mathematical operation used in Poisson probability calculations, multiplying all positive integers up to a given number. Exponential Function
A mathematical term in Poisson formula, involving e raised to a negative mean rate, crucial for probability computation.
