Summary function for 'BATSS' outputs

Summary method function for objects of class 'batss'.

Usage

# S3 method for class 'batss'
summary(object, extended = NULL, ...)

object: An object of class 'batss' (i.e., output of the function batss.glm).
extended: A logical indicating if a standard (extended = FALSE, default) or extended output (extended = TRUE) should be returned. Default to NULL in which case the input of the argument extended chosen when generating object with batss.glm() is used.
...: Additional arguments affecting the summary produced.

Object of class 'summary.batss'.

The function summary.batss returns an S3 list of class 'summary.batss' with available print functions. The list elements are

beta - A data frame providing information related to the beta parameter vector, such as parameter names and values, for example.
look - A data frame providing information related to looks, like sample size of a given interim (m) and cumulative sample size at a given interim (n), for example.
par - A list providing different information, like the used seeds (seed) and the groups (group), for example.
H1 - A list providing trial aggregated results under the alternative, like the probability of efficacy, futility, or both, per arm or globally (object$H1$target), the probability of stopping early for efficacy (object$H1$efficacy) and futility (object$H1$futility), the sample size expectation, standard deviation, and quantiles 0.1, 0.5 and 0.9, per group and overall (object$H1$summary.sample.sizes), the probabilities associated to each combination of efficacy and futility per group (scenario).
H0 - A list providing trial aggregated results under the global null hypothesis (same structure as H1).
call - The matched call.
type - The type of 'BATSS' analysis (only 'glm' is currently available).
