ssim3p3: Simulation of n dose-escalation study with the 3+3 design

Description

The ssim3p3 function simulates n dose-escalation study with the 3+3 design and provides summarized results.

Usage

ssim3p3(truerate, n, r = 2, seed = NULL)

Arguments

truerate

A nlevel-length vector of true rates for the DLTs.

Number of studies to simulate.

Integer, number of digits for percentages in output.

seed

If not empty, the seed to use for random generation.

Value

data

Summarized result in a "np1" view.

norecommendation

Percentage of studies with no recommendation for the MTD (in case of the first level is considered as toxic).

mean.npt

Mean number of enrolled patients.

mean.ndlt

Mean number of observed DLTs.

mean.lastdose

Mean last experimented dose level.
