.em.method | R Documentation |
The varied EM algorithms are implemented in C. The first element is the default value. This is a read-only object and the elemental order is followed in C.
.em.method
A character vector contains implemented EM algorithms in C.
EM
(default) stands for the standard EM algorithm, ECM
stands for Expectation/Conditional Maximization algorithm, and AECM
stands for Alternating ECM algorithm.
The performance is roughly about AECM
> EM
~ ECM
which
are dependent on the separations of data set.
