DnE (version 1.0)

is.dt: is.dt

Description

judge the distribution of the data.

Usage

is.dt(x, m, a)

Arguments

x

data

m

the numbers of intervals of data you wanna devide

a

confidence level

Value

• the distribution of the data

Details

Given a set of observations from a certain distribution, this function is used to test whether the observations are from a distribution of normal distribution or not. The function will work better if the number you choose to devide the interval is between 10 and 20. This number cannot excess the number of given oberservation.
