R: Class "FLXcontrol"

FLXcontrol-class {flexmix} | R Documentation

## Class "FLXcontrol"

### Description

Hyperparameters for the EM algorithm.

### Objects from the Class

Objects can be created by calls of the form `new("FLXcontrol", ...)`. In addition, named lists can be coerced to `FLXcontrol` objects, names are completed if unique (see examples).

### Slots

`iter.max`:

  Maximum number of iterations.

`minprior`:

  Minimum prior probability of clusters, components falling below this threshold are removed during the iteration.

`tolerance`:

  The EM algorithm is stopped when the (relative) change of log-likelihood is smaller than `tolerance`.

`verbose`:

  If a positive integer, then the log-likelihood is reported every `verbose` iterations. If 0, no output is generated during model fitting.

`classify`:

  Character string, one of `"auto"`, `"weighted"`, `"hard"` (or `"CEM"`), `"random"` or (`"SEM"`).

`nrep`:

  Reports the number of random initializations used in `stepFlexmix()` to determine the mixture.

Run `new("FLXcontrol")` to see the default settings of all slots.

### Examples

    ## have a look at the defaults
    new("FLXcontrol")

    ## corce a list
    mycont <- list(iter = 200, tol = 0.001, class = "r")
    as(mycont, "FLXcontrol")
