EstMLECorrBin | R Documentation |
The function will estimate the probability of success and correlation using the maximum log likelihood method for the Correlated Binomial distribution when the binomial random variables and corresponding frequencies are given.
EstMLECorrBin(x,freq,p,cov,...)
x |
vector of binomial random variables. |
freq |
vector of frequencies. |
p |
single value for probability of success. |
cov |
single value for covariance. |
... |
mle2 function inputs except data and estimating parameter. |
x = 0,1,2,...
freq ≥ 0
0 < p < 1
-∞ < cov < +∞
NOTE : If input parameters are not in given domain conditions necessary error messages will be provided to go further.
EstMLECorrBin
here is used as a wrapper for the mle2
function of bbmle package
therefore output is of class of mle2.
