Weighted D Efficiency
Description
wDefficiency
computes the weighted D-, D_s or D_A-efficiency measure for a design with respect to a reference design.
Usage
wDefficiency(des, ref, mods, modw, A = NULL, parNames = NULL)
Arguments
des |
a design. |
ref |
a design, the reference. |
mods |
a list of models. |
modw |
a vector of weights. |
A |
for
|
parNames |
a vector of names or indices, the subset of parameters to use. Defaults to the parameters for which the Fisher information is available. |
Details
Indices supplied to argument A
correspond to the subset of parameters defined by argument parNames
