# fitBin: Fitting the Binomial Distribution when binomial random... In Amalan-ConStat/R-fitODBOD: Modeling Over Dispersed Binomial Outcome Data Using BMD and ABD

## 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

## Examples

 ``` 1 2 3 4 5 6 7 8 9 10``` ```No.D.D=0:7 #assigning the random variables Obs.fre.1=c(47,54,43,40,40,41,39,95) #assigning the corresponding frequencies #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) ```
