R: Artificial Example for Normal Regression

NregFix {flexmix} | R Documentation

## Artificial Example for Normal Regression

### Description

A simple artificial regression example with 3 latent classes, two independent variables, one concomitant variable and a dependent variable which follows a Gaussian distribution.

### Usage

    data("NregFix")

### Format

A data frame with 200 observations on the following 5 variables.

`x1`

  Independent variable: numeric variable.

`x2`

  Independent variable: a factor with two levels: `0` and `1`.

`w`

  Concomitant variable: a factor with two levels: `0` and `1`.

`y`

  Dependent variable.

`class`

  Latent class memberships.

### Examples

    data("NregFix", package = "flexmix")
    library("lattice")
    xyplot(y ~ x1 | x2 * w, data = NregFix, groups = class)
    Model <- FLXMRglmfix(~ 1, fixed = ~ x2,
                         nested = list(k = c(2, 1),
                         formula = c(~x1, ~0)))
    fittedModel <- initFlexmix(y ~ 1, model = Model, data = NregFix, k = 3,
                               concomitant = FLXPmultinom(~ w), nrep = 5)
    fittedModel
