Contains the results of classical Quadratic Discriminant Analysis
Objects can be created by calls of the form new("QdaClassic", ...)
but the
usual way of creating QdaClassic
objects is a call to the function
QdaClassic
which serves as a constructor.
call
:The (matched) function call.
prior
:Prior probabilities used, default to group proportions
counts
:number of observations in each class
center
:the group means
cov
:the group covariance matrices
covinv
:the inverse of the group covariance matrices
covdet
:the determinants of the group covariance matrices
method
:a character string giving the estimation method used
X
:the training data set (same as the input parameter x of the constructor function)
grp
:grouping variable: a factor specifying the class for each observation.
control
:Object of class "CovControl"
inherited from class Qda
specifying which estimate and with what estimation options to use for the group
means and covariances. It is always NULL
for classical discriminant analysis.
Class "Qda"
, directly.
No methods defined with class "QdaClassic" in the signature.
