Class "flexmix"
Description
A fitted flexmix
model.
Slots
model
:- List of
FLXM
objects.
prior
:- Numeric vector with prior probabilities of clusters.
posterior
:- Named list with elements
scaled
and unscaled
, both matrices with one row per observation
and one column per cluster.
iter
:- Number of EM iterations.
k
:- Number of clusters after EM.
k0
:- Number of clusters at start of EM.
cluster
:- Cluster assignments of observations.
size
:- Cluster sizes.
logLik
:- Log-likelihood at EM convergence.
df
:- Total number of
parameters of the model.
components
:- List describing
the fitted components using
FLXcomponent
objects.
formula
:- Object of class
"formula"
.
control
:- Object of class
"FLXcontrol"
.
call
:- The function call
used to create the object.
group
:- Object of class
"factor"
.
converged
:- Logical,
TRUE
if EM algorithm converged.
concomitant
:- Object of class
"FLXP"
..
weights
:- Optional weights of the observations.
Extends
Class FLXdist
, directly.
Accessor Functions
The following functions should be used for accessing the corresponding
slots:

:- Cluster assignments of observations.
posterior
:- A matrix of posterior probabilities for each
observation.
