Description Objects from the Class Slots Extends Methods Author(s) References See Also Examples

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.
