Period to period comparisons in a time series, and detection of the underlying trend which may otherwise be obscured by seasonal and calendar effects. 

Is a visual software package for creating, analysing and communicating quantitative decision models. It combines hierarchical influence diagrams for visual creation and view of models, intelligent arrays for working with multidimensional data, Monte Carlo simulation for analysing risk and uncertainty, and optimization, including linear and nonlinear programming.

Is a statistical package used mainly for time-series oriented econometric analysis. EViews can be used for general statistical analysis and econometric analyses, such as cross-section and panel data analysis and time series estimation and forecasting.

Matrix laboratory is a programming language that allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages.

Is a statistics package developed at the Pennsylvania State University. It is a general-purpose statistical software package used as a primary tool for analysing research data.

Is a system whose programming language and capabilities cover neural networks, machine learning, image processing, geometry, data science, visualizations, and others. 

International unit of temperature equivalent to 5/9 (°F - 32) where °F are degrees Fahrenheit.

Closeness of computations or estimates to the unknown exact or true values that the statistics were intended to measure. 

Assessment of accuracy, linked to a certain Data Set or domain, which is summarising the various components into one single measure. 

Behaviour to be undertaken by a system processing the information contained in a SDMX message. 

Set of procedures employed to modify statistical data to enable it to conform to national or international standards or to address data quality differences when compiling specific Data Sets. 

Maintained collection of maintenance agencies. 

Construct capable of defining Annotations

Construct that contains user or organisation-specific metadata.

Abstract concept denoting an element in the SDMX model having specific characteristics which are inherited by other elements. 

Property of an attribute defining the object to which data or metadata are linked.

Statistical concept providing qualitative information about a specific statistical object. 

Specification of the type of artefact to which a data attribute can be attached in a Data Set. 

Period of time used as the base of an index number, or to which a constant series refers. 

Weight of a weighting system for an index number computed according to the information relating to the base period instead, for example, of the current period. 

Exchange of data and/or metadata between a sending organisation and a receiving organisation where all aspects of the exchange process are agreed between counterparties, including the mechanism for exchange of data and metadata, the formats, the frequency or schedule, and the mode used for communications regarding the exchange. 

Attribute that describes the reason for a break in a time series. 

A data model with a standard and common set of definitions, including data types, data structures, relationships and rules — all independent of any specific application.

Structural metadata concept that links an identifiable object to a Category.

Structural metadata concept that classifies structural metadata objects. 

Descriptive information for a subdivision of categories into groups based on characteristics, which the objects have in common.
