env.concurrent | R Documentation |
"env.concurrent" is an R environment containing the data generated from a concurrent mediation model.
data("env.concurrent")
An R environment
Z
a n\times T
data matrix, treatment trajectory of n
subjects for T
time points.
M
a n\times T
data matrix, mediator trajectory of n
subjects for T
time points.
Y
a n\times T
data matrix, outcome trajectory of n
subjects for T
time points.
alpha
a length T
vector model coefficient.
beta
a length T
vector model coefficient.
gamma
a length T
vector model coefficient.
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.
