Compute simple component criterion for components P
on
cor.matrix S
(cumulative), using sccrit()
.
Function allcrit()
computes even more criteria, some derived
from sccrit()
.
allcrit(S, P, criterion, sortP = TRUE)
sccrit(S, P, criterion, sortP = TRUE)
sccrit()
returns a numeric vector, the criterion computed
(cumulatively).
allcrit()
returns a list with components varpc
,
varsc
, cumpc
, cumsc
, opt
, corsc
,
and maxcor
;
see the description of the allcrit
component in the return value
of sca()
.
correlation/covariance matrix
component matrix
character string specifying the optimality criterion
to be used in sccrit()
for evaluating a system of simple
components. One of "csv"
(corrected sum of variances) or
"blp"
(best linear predictor).
logical indicating if P
should be sorted; if true,
sortmatrix(S,P)
used in lieu of P
.
