Add a latin-hypercube simdesign to a nl object
simdesign_lhs(nl, samples, nseeds, precision)
nl |
nl object with a defined experiment |
samples |
number of samples for the latin hypercube |
nseeds |
number of seeds for this simulation design |
precision |
number of digits for the decimal fraction of parameter values |
This function creates a simdesign S4 class which can be added to a nl object.
Variables in the experiment variable list need to provide a numeric distribution with min, max and qfun (e.g. list(min=1, max=4, qfun="qunif")).
The latin hypercube simdesign creates a parameter matrix based on these defined distributions. Finally, the function reports a simdesign object.
simdesign S4 class object
# To attach a simdesign, a nl object needs to be created first (see ?nl).
# For this example, we load a nl object from test data.
nl <- nl_lhs
nl@simdesign <- simdesign_lhs(nl=nl,
samples=100,
nseeds=3,
precision=3)Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
