Internal function
grid.sim.internal1(n, means = NULL, sigma, grid.param = NULL, pure.sim = FALSE)
row-matrix of parameters
Number of simulations
vector of mean values
covariance matrix
the index of the parameter for which a fix grid (from qnorm) is used instead of a simulated grid (rnorm). If grid.param=NULL ( default) the fix grid will be used for the parameter with largest variance.
