FLXdist-class {flexmix} | R Documentation

## Class "FLXdist"

### Description

Objects of class `FLXdist` represent unfitted finite mixture models.

### Usage

    ## S4 method for signature 'FLXdist':
    parameters(object, component=NULL, model=NULL, which = c("model",
        "concomitant"), simplify=TRUE, drop=TRUE)
    ## S4 method for signature 'FLXdist':
    predict(object, newdata=list(), aggregate=FALSE, ...)

### Arguments

`object` | An object of class "FLXdist".
`component` | Number of component(s), if `NULL` all components are returned.
`model` | Number of model(s), if `NULL` all models are returned.
`which` | Specifies if the parameters of the component specific model or the concomitant variable model are returned.
`simplify` | Logical, if `TRUE` the returned values are simplified to a vector or matrix if possible.
`drop` | Logical, if `TRUE` the function tries to simplify the return object by omitting lists of length one.
`newdata` | Dataframe containing new data.
`aggregate` | Logical, if `TRUE` then the predicted values for each model aggregated over the components are returned.
`...` | Passed to the method of the model class.

### Slots

model
  List of `FLXM` objects.
prior
  Numeric vector with prior probabilities of clusters.
components
  List describing the components using `FLXcomponent` objects.
`concomitant`:
  Object of class `"FLXP"`.
formula
  Object of class `"formula"`.
call
  The function call used to create the object.
k
  Number of clusters.

### Accessor Functions

The following functions should be used for accessing the corresponding slots:

`parameters`:
  The parameters for each model and component, return value depends on the model.
`prior`:
  Numeric vector of prior class probabilities/component weights
