Description Usage Arguments Details Value References Examples
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 l and c.
1 | NegLLGrassiaIIBin(x,freq,a,b)
|
x |
vector of binomial random variables. |
freq |
vector of frequencies. |
a |
single value for shape parameter a. |
b |
single value for shape parameter b. |
0 < a,b
freq ≥ 0
x = 0,1,2,...
NOTE : If input parameters are not in given domain conditions necessary error messages will be provided to go further.
The output of NegLLGrassiaIIBin
will produce a single numeric value.
