Simulated data from the concurrent mediation model
Description
"env.concurrent" is an R environment containing the data generated from a concurrent mediation model.
Usage

Details
The data was generated from the concurrent mediation model
M(t)=Z(t)\alpha(t)+\epsilon_{1}(t),
R(t)=Z(t)\gamma(t)+M(t)\beta(t)+\epsilon_{2}(t).
Z(t)
is the convolution of hemodynamic response function (HRF) and event onsets.
Examples
data(env.concurrent)
Z<-get("Z",env.concurrent)
M<-get("M",env.concurrent)
Y<-get("Y",env.concurrent)
