NegLLGHGBB.Rd
This function will calculate the negative log likelihood value when the vector of binomial random variables and vector of corresponding frequencies are given with the shape parameters a,b and c.
NegLLGHGBB(x,freq,a,b,c)
x | vector of binomial random variables. |
---|---|
freq | vector of frequencies. |
a | single value for shape parameter alpha representing a. |
b | single value for shape parameter beta representing b. |
c | single value for shape parameter lambda representing c. |
The output of NegLLGHGBB
will produce a single numeric value.
$$0 < a,b,c $$ $$freq \ge 0$$ $$x = 0,1,2,...$$
NOTE : If input parameters are not in given domain conditions necessary error messages will be provided to go further.
