qrObj |
A QRMon object. |
threshold |
The threshold to be used to identify anomalies. If NULL the outlier identifier is used. |
outlierIdentifier |
Outlier identifier of list of numbers to be used to identify the anomalies. If NULL an internal implementation of the quartile outlier identifier is used. (For the top outliers.) |
relativeErrorsQ |
Should relative errors be used or not? |
probability |
Which regression quantile to use? If NULL the regression quantile is automatically selected, the one that is closest to 0.5. |
The residuals outliers are picked with the formulas:
c(xL,x0,xU) <- quantile( abs(residuals), c(1/4,1/2,3/4) )
,
abs(residuals) > x0+(xU-xL)
.
(Errors and residuals are used as synonyms here.)
A QRMon object.
