estimateSds.CopyNumberChromosomalModel {aroma.core} | R Documentation |
Estimates the standard deviation of the raw copy numbers (log2-ratios) robustly using a first-order difference variance estimator, which is an estimator that is fairly robust for change points.
## S3 method for class 'CopyNumberChromosomalModel': estimateSds(this, arrays=seq(length = nbrOfArrays(this)), chromosomes=getChromosomes(this), ..., verbose=FALSE)

Returns a CxK double
matrix
where C is the number of chromosomes,
and K is the number of arrays (arrays are always the last dimension).
