DnE (version 2.1.0)

is.unif: is.unif

Description

judge if the data obeys uniform distribution

Usage

is.unif(x, m, a, sita1 = NULL, sita2 = NULL)

Arguments

x

data

m

the number of intervals you want to divide the data in, default value is 10

a

significance level

sita1

distribution parameter, the lower limit of the data

sita2

distribution parameter, the upper limit of the data

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 Uniform 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 function will work better if the number of intervals you choose to divide the data in is between 10 and 20. This number cannot excess the number of given oberservations.
