Examples

# generate data
n <- 500
x <- data.frame(x1 = rnorm(n))
pi.true <- 1 / (1 + exp(.3 + 1.5 * x$x1))
true <- rbinom(n, 1, plogis(pi.true))
dat <- RRgen(n, trueState = true, model = "Warner", p = .1)
x$response <- dat$response

# fit and plot RR logistic regression
mod1 <- RRlog(response ~ x1, data = x, model = "Warner", p = .1)
mod0 <- RRlog(response ~ 1, data = x, model = "Warner", p = .1)
anova(mod1, mod0)
