CovControlMcd | R Documentation |
This function will create a control object CovControlMcd
containing the control parameters for CovMcd
CovControlMcd(alpha = 0.5, nsamp = 500, scalefn=NULL, maxcsteps=200,
seed = NULL, trace= FALSE, use.correction = TRUE)
alpha |
numeric parameter controlling the size of the subsets
over which the determinant is minimized, i.e., |
nsamp |
number of subsets used for initial estimates or For |
scalefn |
|
maxcsteps |
maximal number of concentration steps in the deterministic MCD; should not be reached. |
seed |
starting value for random generator. Default is |
trace |
whether to print intermediate results. Default is |
use.correction |
whether to use finite sample correction factors.
Default is |
