Examples

## performing surivival analysis using the "weibull" family
fit1 <- brm(time | cens(censored) ~ age + sex + disease, 
            data = kidney, family = weibull, inits = "0")
summary(fit1) 
plot(fit1)

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