Implements a normal data distribution for z-values given an observed z-value and stage size. Standard deviation is 1 and mean θ √n where θ is the standardized effect size. The option two_armed can be set to decide whether a one-arm or a two-arm design should be computed.

Normal(two_armed = TRUE)

# S4 method for Normal
quantile(x, probs, n, theta, ...)

# S4 method for Normal,numeric
simulate(object, nsim, n, theta, seed = NULL, ...)

Arguments

two_armed

logical indicating if a two-armed trial is regarded

probs

...

further optional arguments

object

object of class Normal

nsim

number of simulation runs

seed

random seed
