Decode Coded Variables to Plain Text (and Vice Versa)
person("Erik", "Bulow", email = "erik.bulow@rccvast.se",
role = c("aut", "cre"))
Main function "decode" is used to decode coded key values to plain
text. Function "code"" can be used to code plain text to code if there is a
1:1 relation between the two. The concept relies on "keyvalue" objects used
for translation. There are several "keyvalue"" objects included in the areas
of geographical regional codes, administrative health care unit codes,
diagnosis codes et cetera but it is also easy to extend the use by arbitrary
code sets.

and EEMD)
Predict future values with hybrid combinations of Pattern Sequence based
Forecasting (PSF), Autoregressive Integrated Moving Average (ARIMA), Empirical Mode

Export Decomposition (Wang-Wei-Zhu and source)
The R package 'decompr' implements two export decomposition
algorithms. Firstly, the Wang-Wei-Zhu (Wang, Wei, and Zhu 2013) algorithm
splits bilateral gross exports into 16 value added components. Secondly,
the Source decomposition algorithm derives the value added origin of
exports by country and industry, which is also based on Wang, Wei, and Zhu
(2013).
