is.pois: is.pois

Description

judge if the data obey poisson distribution

Usage

is.pois(x, a, lambda = NULL)

Arguments

x

x

a

confidence level

lambda

parameter, the number of successful events in unit time.

Value

• if data obey the distribution, return a value represent the likelihood, the larger the better; else return -1.

Details

Given a set of observations from a certain distribution, this function is used to test whether the observations are from a distribution of possion distribution or not.

is.pois(examplecheck,0.05)
#examplecheck is a dataset with a defined distribution you want to check. Suppose you want the confidence level to be 0.05#
