ts_norm_ean | R Documentation |
Creates a normalization object for time series data using an Exponential Moving Average (EMA) method. This normalization approach adapts to changes in the time series and optionally removes outliers.
ts_norm_ean(remove_outliers = TRUE, nw = 0)
remove_outliers |
logical: if TRUE (default) outliers will be removed. |
nw |
windows size |
returns a ts_norm_ean
object.
# time series to normalize
data(sin_data)
# convert to sliding windows
ts <- ts_data(sin_data$y, 10)
ts_head(ts, 3)
summary(ts[,10])
# normalization
preproc <- ts_norm_ean()
preproc <- fit(preproc, ts)
tst <- transform(preproc, ts)
ts_head(tst, 3)
summary(tst[,10])
