Hi,

I am wondering how I should interpreate the output of optFederov() in AlgDesign.

Specially I want to know what is $D, $A, $Ge and $Dea, which one I can use as an efficiency to say how good the optimal design is.

I only know when a orthogonal design comes, $D = 1.

I red the pdf document    --   vignette("AlgDesign")

[Just type: vignette("AlgDesign") in R, you will get this pdf document]

On page 20 section 4.2.1.3, it says: the D and G efficiencies of the following ... are 98% and 89%. 

I tried the code as shown on page 20 a few times and output showed different designs but the figure of $D, $A, $Ge and $Dea are similar. I don't see $D is close to 0.98, but $Ge is 0.89. One of the output as below:




> dat = gen.factorial(3, 3, center = T, varNames = c("A", "B", "C"))
> desC = optFederov(~quad(A,B,C), dat, nT = 14, evaluateI = T, nR = 100)
> desC
$D
[1] 0.4630447

$A
[1] 3.22

$I
[1] 9.945833

$Ge
[1] 0.893

$Dea
[1] 0.887

$design
    A  B  C
1  -1 -1 -1
3   1 -1 -1
5   0  0 -1
7  -1  1 -1
9   1  1 -1
11  0 -1  0
13 -1  0  0
15  1  0  0
17  0  1  0
19 -1 -1  1
21  1 -1  1
23  0  0  1
25 -1  1  1
27  1  1  1

$rows
 [1]  1  3  5  7  9 11 13 15 17 19 21 23 25 27
 
Thanks very much!
J
