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 CopyNumberChromosomalModel
estimateSds(this, arrays=seq_len(nbrOfArrays(this)), chromosomes=getChromosomes(this),
..., verbose=FALSE)
The arrays to be queried.
The chromosomes to be queried.
Additional arguments passed to
*extractRawCopyNumbers()
.
See Verbose
.
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).
