simdesign_eFast: Add an eFast simdesign to a nl object

Description

Add an eFast simdesign to a nl object

Usage

simdesign_eFast(nl, samples, nseeds)

Value

simdesign S4 class object

Arguments

nl

nl object with a defined experiment

samples

number of samples for the eFast sensitivity analysis

nseeds

number of seeds for this simulation design

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 eFast simdesign uses the sensitivity package to set up a fast99 elementary effects sensitivity analysis, including a simobject of class fast99 and a input tibble for simulations. For details on method specific sensitivity analysis function parameters see ?fast99 Finally, the function reports a simdesign object.

Examples

# 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_eFast
nl@simdesign <- simdesign_eFast(nl=nl,
                                 samples=100,
                                 nseeds=1)
