TERROR Quality Control of Outliers

TRAMO for ERRORs (TERROR) controls the quality of the data by checking outliers at the end of the series

Usage

terror(
  ts,
  spec = c("trfull", "tr0", "tr1", "tr2", "tr3", "tr4", "tr5"),
  nback = 1,
  context = NULL
)

Arguments

ts

a univariate time series.

spec

the model specification. Can be either the name of a predefined specification or a user-defined specification.

nback

number of last observations considered for the quality check.

context

the dictionary of variables.

Value

a mts object with 7 variables:

1. actual: the actual data at the end of the series;

2. forecast: the forecast of the actual data at the end of the series;

3. error: the absolute errors (= observed - forecasts);

4. rel.error: relative errors ("scores") : ratios between the forecast errors and the standard deviation of the forecasts of the last observations (positive values mean under-estimation);

5. raw: the transformed series. More especially, if the chosen model implies a log-transformation, the values are obtained after a log-transformation. Other transformations, such leap year corrections or length-of periods corrections may also be used;

6. fraw: the forecast of the transformed series.;

7. efraw: the absolute errors of the transformed series.

Examples

if (FALSE) { # current_java_version >= minimal_java_version
# \donttest{
terror(rjd3toolkit::ABS$X0.2.09.10.M, nback = 2)
# }
