Implementation of crossover matrix

Given a design of a hypothetical cluster randomized stepped wedge study and their pattern of fidelity over time conduct the function the corresponding design matrix which can be used for linear regression modeling

Usage

implemMatrix.crossover(nC, nT, nSw, swP = NULL, pattern)

Arguments

nC

Number of cluster

nT

Number of time points

nSw

Number of cluster with switches from control condition 0 to treatment condition 1 at each time point

swP

Number of timepoints the for clusters be at control

pattern

Fidelity pattern (deviation from 1) for each time point

Value

Design matrix of size nT x nC for a cross-over cluster randomized trial with values of 0 for control condition and values between 0 and 1 for degree of implementation of treatment (fidelity)' @return
