get_example_statistics {adestr}

Generate a list of estimators and p-values to use in examples

Description

This function generates a list of objects of class PointEstimator, IntervalEstimators, and PValues to use in examples of the analyze function.

Usage

  point_estimators = TRUE,
  interval_estimators = TRUE,
  p_values = TRUE
)

Arguments

Examples

set.seed(123)
dat <- data.frame(
  endpoint = c(rnorm(28, 0.3)),
  stage = rep(1, 28)
)
analyze(data = dat,
        statistics = list(),
        data_distribution = Normal(FALSE),
        design = get_example_design(),
        sigma = 1)

# The results suggest recruiting 32 patients for the second stage
dat <- rbind(
  dat,
  data.frame(
    endpoint = rnorm(32, mean = 0.3),
    stage = rep(2, 32)))
analyze(data = dat,
        statistics = get_example_statistics(),
        data_distribution = Normal(FALSE),
        design = get_example_design(),
        sigma = 1)
