| estimateStandardDeviation.RawGenomicSignals {aroma.core} | R Documentation |
Estimates the standard deviation of the raw Ys robustly or non-robustly using either a "direct" estimator or a first-order difference estimator.
## S3 method for class 'RawGenomicSignals':
estimateStandardDeviation(this, method=c("diff", "direct"), estimator=c("mad", "sd"), na.rm=TRUE, weights=getWeights(this), ...)
method |
If "diff", the estimate is based on the first-order
contigous differences of raw Ys. If "direct", it is based
directly on the raw Ys. |
estimator |
If "mad", the robust mad estimator
is used. If "sd", the sd estimator is used. |
na.rm |
If TRUE, missing values are excluded first. |
weights |
Locus specific weights. |
... |
Not used. |
Returns a non-negative numeric value.
