Introduction

The Quick Start aims to introduce the JDemetra+ 2.x software, which enables the user to perform seasonal adjustment and other operations. The Quick Start gives working instructions on how to install and launch the software. It includes a step-by-step description of how to perform the first analysis with JDemetra+. The dataset used in the Quick Start to illustrate the JDemetra+ functionalities is accessible here and can be used to replicate the results presented in theis section.

The Quick Start is intended for beginners, who have only a basic knowledge of seasonality and its estimation in time series. Therefore, the case study included in this document is a basic one. For decription of more advanced examples refer to the Case studies. Information about the JDemetra+ software and its functionalities can be found in the Reference Manual.

It is assumed that the reader is familiar with time series related concepts. Readers with insufficient background to follow this document are encouraged to refer to an appropriate textbook, e.g. CHATFIELD (2004).

The Quick Start neither describes in detail how the seasonal adjustment methods work, nor the underlying mathematics. For the readers interested in studying seasonal adjustment methods brief sketches of the X-13ARIMA-SEATS and TRAMO-SEATS algorithms and concepts as well as a bibliography are included in this Wiki.
