twostage.admissible function

Admissible design options between Minimax and Optimal

Lists the admissible design options between

twostage.admissible(x)

Arguments

• x: output from ph2simon call

Returns

twostage.admissible returns design options that are admissible (Jung et al, 2004). The output is a matrix with 8 columns: r1, n1, r, n, EN(p0), PET(p0), qLo, qHi. The columns qLo and qHi give the range of probability values for which the particular design is admissible.
