kidney {brms} | R Documentation

## Infections in kidney patients

### Description

This dataset, originally discussed in McGilchrist and Aisbett (1991), describes the first and second (possibly right censored) recurrence time of infection in kidney patients using portable dialysis equipment. In addition, information on the risk variables age, sex and disease type is provided.

### Usage

    kidney

### Format

A data frame of 76 observations containing information on the following 7 variables.

time

  The time to first or second recurrence of the infection, or the time of censoring

recur

  A factor of levels `1` or `2` indicating if the infection recurred for the first or second time for this patient

censored

  Either `0` or `1`, where `0` indicates no censoring of recurrence time and `1` indicates right censoring

patient

  The patient number

age

  The age of the patient

sex

  The sex of the patient

disease

  A factor of levels `other, GN, AN`, and `PKD` specifying the type of disease

### Examples

    ## Not run:
    ## performing surivival analysis using the "weibull" family
    fit1 <- brm(time | cens(censored) ~ age + sex + disease,
                data = kidney, family = weibull, init = "0")
    summary(fit1)
    plot(fit1)

    ## adding random intercepts over patients
    fit2 <- brm(time | cens(censored) ~ age + sex + disease + (1|patient),
                data = kidney, family = weibull(), init = "0",
                prior = set_prior("cauchy(0,2)", class = "sd"))
    summary(fit2)
    plot(fit2)
