estimateSds.CopyNumberChromosomalModel: Estimates the standard deviation of the raw copy numbers (log2-ratios) robustly

Description

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.

Usage

## S3 method for class 'CopyNumberChromosomalModel':
estimateSds(this, arrays=seq_len(nbrOfArrays(this)), chromosomes=getChromosomes(this),
  ..., verbose=FALSE)

Arguments

arrays

The arrays to be queried.

chromosomes

The chromosomes to be queried.

...

Additional arguments passed to *extractRawCopyNumbers().

verbose

See Verbose.

Value

• 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).
