DnE (version 2.1.0)

is.geom: is.geom

Description

judge if the data obeys geometric distribution.

Usage

is.geom(x, a, p0 = NULL)

Arguments

x

data

a

significance level

p0

the pobability of success

Value

Details

Given a set of observations from a certain distribution, this function is used to test whether the observations are from a distribution of Geometric distribution or not. Usually, to ensure the function works well, the sample size needs to be large enough, i.e. the result will be stable if the sample size is larger than 100. The Geometric distribution mentioned in this function is defined as the repetition of Bernoulli when the first success occurs. The observations of geometric distribution must be positive integer.
