samediffSim {sensR}

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.
