Description Usage Arguments Details Value Examples

View source: R/Data.R

Description

The function will fit the binomial distribution when random variables, corresponding frequencies and probability value are given. It will provide the expected frequencies, chi-squared test statistics value, p value and degree of freedom so that it can be seen if this distribution fits the data.

Usage

1
fitBin(x,obs.freq,p=0,print=T)

Arguments

x

vector of binomial random variables

obs.freq

vector of frequencies

p

single value for probability

print

logical value for print or not

Details

x = 0,1,2,...

0 ≤ p ≤ 1

obs.freq ≥ 0

NOTE : If input parameters are not in given domain conditions necessary error messages will be provided to go further.

Value

The output of fitBin gives a list format consisting

bin.ran.var binomial random variables

obs.freq corresponding observed frequencies

exp.freq corresponding expected frequencies

statistic chi-squared test statistics value

df degree of freedom

p.value probability value by chi-squared test statistic

#fitting when the random variable,frequencies,probability value are given.
fitBin(No.D.D,Obs.fre.1,p=0.7)

fitBin(No.D.D,Obs.fre.1,p=0.7,FALSE)$exp.freq  #extracting the expected frequencies

#fitting when the random variable,frequencies are given.
fitBin(No.D.D,Obs.fre.1)
