fitBin {fitODBOD} | R Documentation |
Fitting the Binomial Distribution when binomial random variable, frequency and probability value are given
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
fitBin(x,obs.freq,p=0)
Arguments
x |
vector of binomial random variables. |
obs.freq |
vector of frequencies. |
p |
single value for probability. |
Details
x = 0,1,2,...
0 \le p \le 1
obs.freq \ge 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 the class format fitB
and fit
consisting a list
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.
fitB
fitted probability values of dbinom
.
phat
estimated probability value.
call
the inputs of the function.
Examples
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 are given.
fitBin(No.D.D,Obs.fre.1)
