SurvivalDesign

SurvivalDesign is a function that converts an arbitrary design to a survival design.

Usage

SurvivalDesign(design, event_rate)

# S4 method for class 'TwoStageDesign'
SurvivalDesign(design, event_rate)

# S4 method for class 'TwoStageDesign'
TwoStageDesign(n1, event_rate)

# S4 method for class 'OneStageDesign'
OneStageDesign(n, event_rate)

# S4 method for class 'OneStageDesign'
SurvivalDesign(design, event_rate)

# S4 method for class 'GroupSequentialDesign'
GroupSequentialDesign(n1, event_rate)

# S4 method for class 'GroupSequentialDesign'
SurvivalDesign(design, event_rate)

Arguments

design

design that should be converted to a survival design

event_rate

probability that a subject in either group will eventually have an event

n1

design object to convert (overloaded from TwoStageDesign)

n

design object to convert (overloaded from TwoStageDesign)

Value

Converts any type of design to a survival design

Examples

design <- get_initial_design(0.4, 0.025, 0.1)
SurvivalDesign(design, 0.8)
#> TwoStageDesignSurvival<n_events1=72;0.0<=x1<=2.2;n_events2=33-182> 

design_os <- get_initial_design(0.4, 0.025, 0.1, type_design = "one-stage")
design_gs <- get_initial_design(0.4, 0.025, 0.1, type_design = "group-sequential")

OneStageDesign(design_os, 0.7)
#> OneStageDesignSurvival<n_events=131;c=1.96> 

GroupSequentialDesign(design_gs, 0.8)
#> GroupSequentialDesignSurvival<n_events1=72;0.0<=x1<=2.2;n_events2=72>
