Like NMsim_default but `$THETA`, `$OMEGA`, and `SIGMA` are
drawn from distribution estimated in covariance step. A successful
covariance step must be available from the estimation. In case the
simulation leads to negative diagonal elements in $OMEGA and
$SIGMA, those values are truncated at zero. For simulation with
parameter variability based on bootstrap results, use
NMsim_default.
This function does not run any simulations. To simulate, using this method, see `NMsim()`.
NMsim_VarCov(file.sim, file.mod, data.sim, nsims, ext, write.ext = NULL)Character vector of simulation control stream paths
The path to the control stream to be edited. This function overwrites the contents of the file pointed to by file.sim.
Path to the path to the original input control stream provided as `file.mod` to `NMsim()`.
Included for compatibility with `NMsim()`. Not used.
Number of replications wanted. The default is 1. If greater, multiple control streams will be generated.
Parameter values in long format as created by `readParsWide` and `NMdata::NMreadExt`.
If supplied, a path to an rds file where the parameter values used for simulation will be saved.
