Seasonal adjustment is an important step of the official statistics business architecture and harmonisation of practices has proved to be key element of quality of the output. In this spirit, since the 90s, Eurostat has been playing a role in the promotion, development and maintenance of a software solution (Demetra) freely available for seasonal adjustment in line with established best practices. In 2008, ESS (European Statistical System) guidelines on SA have been endorsed by the CMFB and the SPC as a framework for seasonal adjustment of PEEIs and other ESS and ESCB economic indicators. ESS guidelines cover all the key steps of the seasonal and calendar adjustment process and represent an important step towards the harmonisation of seasonal and calendar adjustment practices within the ESS and in Eurostat. A common policy for the seasonal and calendar adjustment of all infra-annual statistics will improve the quality and comparability of the national data as well as enhance the overall quality of European to the extent that proper SA tools exist and are available.
The SA Steering Group (the Eurostat-ECB high level group of experts from NSIs and NCBs which has produced the ESS Guidelines for seasonal adjustment) is promoting the development of a flexible software solution for SA to be used within the ESS. The group has drawn its attention on the object oriented technologies used by the R&D Unit of the Department of Statistics of the National Bank of Belgium to develop a series of prototype tools for SA. This has been considered as an adequate framework for the cooperative development of a new generation of sustainable SA tools, enabling the implementation of the ESS guidelines and replacing the previous Demetra whose maintenance and sustainability is put in question. Demetra+ is a family of modules on seasonal adjustment, which are based on the two leading algorithms in that domain (TRAMO&SEATS@ / X-12-ARIMA). TRAMO&SEATS@ (TRAMO 'Time series Regression with ARIMA noise, Missing values and Outliers ', and SEATS, 'Signal Extraction in ARIMA Time Series ', developed by Agust铆n Maravall and Victor G贸mez) and X-12-ARIMA (developed by David Findley and Brian Monsell) are two different methods to seasonally adjust a time series. Both methods can be divided into two main parts: a pre-adjustment step, which removes the 'deterministic ' component of the series by means of a regression model with Arima noises and the decomposition part itself. The two methods use a very similar approach in the first part of the processing but they differ completely in the decomposition part.
Their comparison is often difficult, even for the modelling step. More especially, their diagnostics focus on different aspects and their outputs take completely different forms. One of the main features of Demetra+ is to normalize - as much as possible - the different methods. It tries to improve the comparability of the two methods by using as much as possible, a common set of diagnostics and of presentation tools.
That fundamental choice implies that a number of routines of both methods have been re-written in Demetra+. That can lead, compared to the original programs, to small discrepancies in diagnostics or in peripheral information that should not alter the general 'message ' provided by the algorithms. Under no circumstances should the main results of the original programs (seasonally adjusted series.) be impacted by that solution.
File type: Detailed Analysis Project We'll show you how to view a DM2 file you found on your computer or received as an email attachment, and what it's for. What is a DM2 file? The DM2 file type is primarily associated with Demetra by European Commission (Eurostat).
Demetra was developed to ease the access of non-specialists and specialists in time-series statistics to the packages Tramo/Seats and X-12-Arima and to improve their user-friendliness. Demetra imposes a recognised seasonal adjustment policy, and follows standard practice of seasonal adjustment. How to open a DM2 file? You need a suitable software like Demetra to open a DM2 file. Without proper software you will receive a Windows message ' How do you want to open this file?' (Windows 10) or ' Windows cannot open this file' (Windows 7) or a similar Mac/iPhone/Android alert.
If you cannot open your DM2 file correctly, try to right-click or long-press the file. Then click 'Open with' and choose an application. Programs that open and convert DM2 files:.

How to solve problems with DM2 files?. Associate the DM2 file extension with the correct application. On,.
Update your software that should actually open Detailed Analysis Projects. Because only the current version supports the latest DM2 file format.
Search, therefore, e.g. On the manufacturer website after an available Demetra update. To make sure that your DM2 file is not corrupted or virus-infected, get the file again and scan it with Google's.
