simulate.brmultinom {brglm2} | R Documentation

## Method for simulating a data set from `brmultinom` and `bracl` objects

### Description

Method for simulating a data set from `brmultinom` and `bracl` objects

### Usage

    ## S3 method for class 'brmultinom'
    simulate(object, ...)

### Arguments

`object` | an object of class `brmultinom` or `bracl`.
`...` | currently not used.

### Value

A `data.frame` with `object$ncat` times the rows that `model.frame(object)` have and the same variables. If `weights` has been specified in the call that generated `object`, then the simulate frequencies will populate the weights variable. Otherwise, the resulting `data.frame` will have a `".weights"` variable with the simulated multinomial counts.

### Examples

    ## Multinomial logistic regression
    data("housing", package = "MASS")
    houseML1 <- brmultinom(Sat ~ Infl + Type + Cont, weights = Freq,
                           data = housing, type = "ML", ref = 1)
    simulate(houseML1)

    ## Adjacent-category logits
    data("stemcell", package = "brglm2")
    stemML1 <- bracl(research ~ religion + gender, weights = frequency,
                    data = stemcell, type = "ML")

    simulate(stemML1)
