simdesign_lhs: Add a latin-hypercube simdesign to a nl object

Description

Add a latin-hypercube simdesign to a nl object

Usage

simdesign_lhs(nl, samples, nseeds, precision)

Arguments

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

Value

simdesign S4 class object

Details

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.

Examples

# NOT RUN {
# 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)
