The elements of PARAM
or PARAM.org
are
N |
number of observations |
p |
dimension of each observation,
total number of variables |
K |
number of clusters |
ETA |
mixing proportion |
log.ETA |
log of mixing proportion |
MU |
centers, dim =
\(p \times K\) |
SIGMA |
dispersions, a list containing \(K\)
elements, each element is a matrix,
dim = \(p \times p\) |
U |
Choleski of SIGMA, the same size of
SIGMA |
U.check |
checks of each elements of U,
length \(K\) |
logL |
log likelihood |
The model parameters are ETA
, MU
, and SIGMA
, while
log.ETA
, U
, U.check
, and min.N.CLASS
are only used in computing.
