Options for the Robust Outlier Covariance Estimator

Build a checked record of extra arguments for robustbase::covMcd(), the minimum-covariance-determinant estimator behind outlierAction = "drop" on molecularTraits and residualizedPhenotypes.

Usage

CovMcdOptions(...)

Arguments

...

Arguments for robustbase::covMcd() – in practice alpha (the subset fraction the determinant is minimised over, which sets the breakdown point), nsamp, use.correction and nmini / kmini. x is the trait matrix pecotmr assembles and is refused, as is seed: pecotmr owns RNG reproducibility, and covMcd()'s seed restores the ambient .Random.seed on exit, which would silently undo the caller's stream.

Value

A MethodOptions record for the outlierArgs argument.
