Hi,
I am using the methods developped in the packages "statDA and
mvoutliers" to detect multivariate outliers.
I used the "plotmvoutlier" to detect the outliers.
The only thing I don't understand is that the results given by
the vector "w" from "arw" and "o" from "plotmvoutlier" are not the
same (i.e. : w != o is not equal to true)
Should they be the same or not (or just the opposite) for the same
parameters?
if not, what is the meaning of the "w" vector ?
Here is an example of my code :
rob <- covMcd(BoxCoxData, alpha = 0.75)
xarw <- arw(BoxCoxData, rob$center,rob$cov, alpha = 0.01)
mvOut <- plotmvoutlier(Coord,Data, quan=0.75, alpha=0.01, plotmap=FALSE)
xarw$w == !mvOut$o
Thanks.
