Examples

# set dimensions (p=covariates, n=individuals, T=time points)
p <- 3; n <- 4; T <- 10

# set model parameters
SigmaE <- diag(p)/4
A      <- createA(p, "chain")

# generate data
Y <- dataVAR1(n, T, A, SigmaE)

# convert data to a longitudinal-object
Ylongitudinal <- array2longitudinal(Y)

# convert back to array-format
Yback <- longitudinal2array(Ylongitudinal)
