loglk_full {gmmsslm} | R Documentation |
Full log-likelihood function
Description
Full log-likelihood function with both terms of ignoring and missing
Usage
loglk_full(dat, zm, pi, mu, sigma, xi)
Arguments
dat |
An |
zm |
An n-dimensional vector containing the class labels including the missing-label denoted as NA. |
pi |
A g-dimensional vector for the initial values of the mixing proportions. |
mu |
A |
sigma |
A |
xi |
A 2-dimensional vector containing the initial values of the coefficients in the logistic function of the Shannon entropy. |
Details
The full log-likelihood function can be expressed as
whereis the log likelihood function formed ignoring the missing in the label of the unclassified features,
and
is the log likelihood function formed on the basis of the missing-label indicator.
