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.
