What is the statistical analysis system?
The term “statistical analysis” is used to indicate a software that allows the user to perform statistical analysis on data files. Another commonly used term for this type of software is the statistical programming language. In capitalization, the SAS system (SAS) system is also the name of one of the most famous software packages of this type.
The statistical analysis system provides automation and processing power needed to facilitate the handling and analysis of data files. These packages make it easier to calculate descriptive and induction statistics. Commonly used descriptive statistical calculations include the calculation of central tendencies, the distribution of frequency and the association. Inductive statistical analysis, which can be performed with a system of statistical analysis, includes statistical testing of hypotheses such as T-test, test Z and Chi-Kvadrate test. Many statistical analysis systems also support other tests such as Variament Analysis and its relatives and various types of regression tests. MostThe users of these types of software packages are natural and social scientists in the environment of academic and commercial research. Businesses can also use a system of statistical analyzes for operational research, project management and other business news applications.
For some software packages, the command line interface (CLI) is more often used, while others are primarily contained by the graphical user interface (GUI), often with drop -down menus. Most software packages provide CLI and GUI capabilities, although the user may not have access to all features from both interfaces. While GUI is more familiar to non -technical users, the use of CLI to create programs allows easier replication of analyzes.
Many statistical softwjsou packages use fourth generation programming languages (4GL). Due to their higher levels of abstraction and more natural syntax is handling and analysis of data in 4GL RychlMore and easier than in lower -level programming languages. Before developing 4GL, statistical analysis supported by computer was cumbersome and required more professional knowledge of programming.
A large number of software applications of statistical analysis with different interfaces, abilities and extensions are available. Proprietary software applications remain popular, but many open source software applications are also widely used. Virtually all statistical software packages will run in Windows® operating systems, and most of them also have Macintosh® and Linux® versions. Several applications are also compatible with UNIX® operating systems.
