Plugins
A plugin is a software component that can extend JDemetra+ functionalities.
Plugins can be shared between the users and installed individually. The installation procedure is decribed in the dedicated item of the Reference Manual section.
The list below presents the plugins developed by the Bundesbank and the National Bank of Belgium.
Bundesbank plug-ins
| Plug-in | Short Description | |
|---|---|---|
| ConCur | The plug-in ConCur supports the controlled current adjustment approach. It supports the storage of the current components and offers graphical tools to compare forecasted and re-estimated figures. Furthermore, a pre-defined summary of the output containing the most important quality measures can be exported to HTML files. | |
| KIX | The plug-in KIX (German for chain-linked index) has been designed to facilitate the handling of this index type. It offers addition and subtraction of two or more chain-linked time series as well as the computation of contributions of growth. | |
| KIX2.0 | KIX 2.0 offers addition and subtraction of two or more chain-linked time series as well as the computation of contributions of growth following the concept of annual overlap. Contributions to growth are calculated with the partial contribution to growth approach. | |
| KIXE | KIX_E offers addition and subtraction of two or more chain-linked time series as well as the computation of contributions of growth following the concept of one-period overlap. Contributions to growth are calculated with the aid of the Ribe (1999) contribution to growth approach. | |
| KIX‑CC | The program KIX-CC offers for continuously chain-linked indices the aggregation or disaggregation of two or more indices, or the calculation of contributions to growth. | |
| SpecParser | The plug-in SpecParser is designed to migrate already existing specification files (X-12-ARIMA compatible .spc- and .mta-(meta)-files) to JD+. The plugin automatically translates all relevant information (e.g. time series data, regression variables, specifications) from the X-12-ARIMA spc-files and constructs an analogous seasonal adjustment document in JD+. | |
| TransReg | The plug-in TransReg allows the user to carry out grouping and centring of user-defined regression variables in JD+. | |
| Xlsx2Ws | The plug-in Xlsx2Ws allows the converting of specific workspace information to a xlsx file and vice versa. | |
National Bank of Belgium plug-ins
| Plug-in | Short Description | |
|---|---|---|
| Access | This JDemetra+ extension is a pure java library for reading time series from MS Access databases. It currently supports versions 2000-2016 read/write and 97 read-only. Being a pure Java library, you don't need MS Access installed in order to read Access files. |
|
| SDMX | This plugin provides time series from SDMX to JDemetra+ by querying web services or parsing files. | |
| SA Advanced | This module provides some experimental seasonal adjustment methods (with RegArima preprocessing): basic structural models, generalized airline models and airline + seasonal noise models (called mixed airline) |
|
| gairline | Generalized airline model | |
| mairline | Mixed airline model | |
| mixedfreq | Mixed frequencies seasonal adjustment | |
| sssts | Seasonal specific structural time series | |
| sts | Structural time series | |
| Benchmarking | This module provides some experimental methods for temporal disaggregation and multi-variate benchmarking: Chow-Lin, Fernandez, Litterman, Cholette, Calendarization... |
|
| Nowcasting | Nowcasting is often defined as the prediction of the present, the very near future and the very recent past. The plug-in developed at the National Bank of Belgium helps to operationalize the process of nowcasting. It can be used to specify and estimate dynamic factor models and visualize how the real-time dataflow updates expectations, as for instance in Banbura and Modugno (2010). The software can also be used to perform pseudo out-of-sample forecasting evaluations that consider the calendar of data releases, contributing to the formalization of the nowcasting problem originally proposed by Giannone, et al. (2008) or Evans (2005). | |
