tsoutliers: Identify and replace outliers in a time series
Description
Uses supsmu for non-seasonal series and a periodic stl decomposition with
seasonal series to identify outliers and estimate their replacements.
Usage
tsoutliers(x, iterate = 2, lambda = NULL)
Arguments
x
time series
iterate
the number of iteration only for non-seasonal series
lambda
Box-Cox transformation parameter. If lambda="auto",
then a transformation is automatically selected using BoxCox.lambda.
The transformation is ignored if NULL. Otherwise,
data transformed before model is estimated.
Value
index
Indicating the index of outlier(s)
replacement
Suggested numeric values to replace identified outliers
