Simulate from multivariate MixAR models
mixVAR_sim.RdSimulate data from multivariate MixAR models under the assumptions of multivariate Gaussian innovarion
Arguments
- model
model from which to simulate, an object inheriting from class
MixVAR.- n
size of simulated multivariate series.
- init
initial values, a numeric matrix. If
missing, a matrix of 0 values is generated.- nskip
number of burn-in values.
- flag
if
TRUEreturns also the regimes.
Details
mixVAR_sim simulates a series of length nskip + n and returns
the last n values. init provides initial values for the
algorithm. Each row is considered as a time point. The number of rows
must be at least equal to the maximal AR order.
Examples
AR <- list()
AR[[1]] <- array(c(0.5,-0.3,-0.6,0,0,0.5,0.4,0.5,-0.3), dim = c(3,3,1))
AR[[2]] <- array(c(-0.5,0.3,0,1,0,-0.5,-0.4,-0.2, 0.5), dim = c(3,3,1))
prob <- c(0.75, 0.25)
shift <- cbind(c(0,0,0), c(0,0,0))
Sigma1 <- cbind(c(1, 0.5, -0.4), c(0.5, 2, 0.8), c(-0.4, 0.8, 4))
Sigma2 <- cbind(c(1,0.2, 0), c(0.2, 2, -0.15), c(0, -0.15, 4))
Sigma <- array(c(Sigma1, Sigma2), dim = c(3,3,2))
m <- new("MixVARGaussian", prob=prob, vcov=Sigma, arcoef=AR, shift=shift)
