Regularize n1

N1 is a class that computes the n1 value of a design. This can be used as a score in minimize.

N1(label = NA_character_)

# S4 method for N1,TwoStageDesign
evaluate(s, design, optimization = FALSE, ...)

Arguments

label

object label (string)

s

Score object

design

object

optimization

logical, if TRUE uses a relaxation to real parameters of the underlying design; used for smooth optimization.

...

further optional arguments

Value

an object of class N1

Examples

n1_score <- N1()

evaluate(
   N1(),
   TwoStageDesign(70, 0, 2, rep(60, 6), rep(1.7, 6))
) # 70
#> [1] 70
