Description Usage Arguments Details Value
This function generates a single 2-level design with the specified number of runs and factors. The design is optimized for the criterium that is specified by the parameters alpha_i.
1 2 | Doptimize(N, k, nrestarts, alpha1 = 1, alpha2 = 0, alpha3 = 0,
verbose = 1, method = 0, niter = 1e+05, maxtime = 500)
|
N |
Number of runs |
k |
Number of factors |
nrestarts |
Number of restarts to generated an optimal design |
alpha1 |
Parameter of the optimization function |
alpha2 |
Parameter of the optimization function |
alpha3 |
Parameter of the optimization function |
verbose |
Integer that determines the amount of debug output |
method |
Integer, default: 0. The method 0 uses updates of single elements of the design matrix. The method 1 uses swaps of 2 elements of the matrix. |
niter |
Integer (maximum number if iteration steps in the optimization) |
maxtime |
Float (maximum running time before aborting the optimization) |
The criterium that is optimized is: F = alpha1*D + alpha2*Ds + alpha3 * D1
Here D is the D-efficiency of the design and Ds and D1 other efficiency measures. The values alpha_i are scalar parameters. For more details see http://pietereendebak.nl/oapackage/Doptim.html
