EMexample | R Documentation |
A model-based clustering based on parameterized finite Gaussian mixture models
data(EMexample)
an object of class Mclust
providing the optimal (according
to BIC) mixture model estimation composed of 5 clusters.
The details of the output components are as follows:
call
the matched call
data
a matrix
, the input data matrix
modelName
a character
string denoting the model at
which the optimal BIC occurs
n
an integer
, the number of observations in the data
d
a double
, the dimension of the data
G
an integer
, the optimal number of mixture
components
BIC
a double
, all BIC values
bic
a double
, the optimal BIC value
loglik
a double
, the log-likelihood corresponding
to the optimal BIC
df
a double
, the number of estimated parameters
hypvol
NA
parameters
a list
with the following components:
pro
a vector
of double
whose k
th
component is the mixing proportion for the k
th component
of the mixture model
mean
a matrix
of double
whose k
th
column is the mean of the k
th component of the mixture model
variance
a list
of variance parameters for
the model
z
a matrix
of double
whose
[i,k]
th entry is the probability that observation i
in
the test data belongs to the k
th class
classification
an array
of double
, the
classification corresponding to z
uncertainty
a double
, the uncertainty associated
with the classification
