'X11' Extreme Values Corrector

x11_extreme_values_corr(
  x,
  corrected_s,
  period,
  lsigma = 1.5,
  usigma = 2.5,
  mul = FALSE,
  start = 0,
  clean_extremities = TRUE
)

Arguments

x: the analysed time series.
corrected_s: other time series if the series being corrected is different from x.
period: the period of the input time series if x is not a "ts" object.
lsigma, usigma: the lower and the upper sigma boundaries for the detection of extreme values.
mul: boolean indicating if the decomposition is multiplicative or additive.
start: position of the first "complete" considered period.
clean_extremities: boolean indicating if the extremities should be cleaned.

The 'X11' Extreme Values Corrector is used to compute the tables b4, b4g, b9, b9g, b17, b20, c17 and c20.
