## Formula interface for function `CoxBoost` of package `CoxBoost`.

### Description

Formula interface for function `CoxBoost` of package `CoxBoost`.

### Usage

    coxboost(formula, data, cv = TRUE, cause = 1, penalty, ...)

### Arguments

`formula` | An event-history formula for competing risks of the form `Hist(time,status)~sex+age` where `status` defines competing events and right censored data. The code for right censored can be controlled with argument `cens.code`, see man page the function `Hist`.
`data` | A data.frame in which the variables of formula are defined.
`cv` | If `TRUE` perform cross-validation to optimize the parameter `stepno`. This calls the function `cv.CoxBoost` whose arguments are prefix controlled, that is `cv.K=7` sets the argument `K` of `cv.CoxBoost` to `7`. If `FALSE` use `stepno`.
`cause` | The cause of interest in competing risk models.
`penalty` | See `CoxBoost`.
`...` | Arguments passed to either `CoxBoost` via `CoxBoost.arg` or to `cv.CoxBoost` via `cv.CoxBoost.arg`.
