samediffSim: Simulates data from a samediff test

In sensR: Thurstonian Models for Sensory Discrimination

Simulates data from a samediff test

Description

Simulates the outcome of n same-different experiments.

Usage

samediffSim(n, tau, delta, Ns, Nd)

Arguments

n	the number of experiments to simulate.
tau	the value of "tau".
delta	the value of delta (d-prime).
Ns	number of same-samples
Nd	number of different-samples

Details

The function makes two calls to rbinom.

Value

A matrix of with n rows and four columns named ss, ds, sd, dd with the number of same-answers to same-samples, different-answers to same-samples, same-answers to different-samples and different-answers to different-samples respectively.
