I. Analysis and introduction
Analysis is to break things or objects down into parts or attributes in your mind. Although "analysis" as a formal concept has only been gradually established in recent years, this technology has been applied to many fields such as mathematics and logic since Aristotle (384-322 BC).
Analysis can refer to: financial analysis; System analysis; Analytical chemistry; Analytical mechanics; Structural analysis; Model flow analysis; Frequency analysis; Time series analysis; Mathematical analysis; Real analysis; Complex analysis; Harmonic analysis; Functional analysis dimension analysis; Semantic analysis; Voice analysis; Philosophical analysis.
Second, the application of analysis
In the field of information technology, the development of system analysis is relatively mature, which is closely related to the requirements analysis in computer systems and software engineering. With the popularization of computer technology, operational research and the development of system analysis methods such as structured analysis and specification language, system analysis methods have been widely used in interdisciplinary fields and have been used to study, analyze and improve many systems.
Financial analysis, time series analysis and mathematical analysis;
1, financial analysis
Financial analysis (also known as financial analysis) refers to the analysis of enterprises, projects or investments by using financial indicators and methods such as profit rate, solvency, liquidity, stability, growth history and prospects, and peer comparison. Financial analysts can be subdivided into securities (stock) analysts, foreign exchange analysts and gold analysts.
2. Time series analysis
Time series is a series of data points arranged in chronological order. Usually, the time interval of a set of time series is a constant value (such as 1 second, 5 minutes, 12 hours, 7 days, 1 year), so the time series can be analyzed and processed as discrete time data.
3. Mathematical analysis
Mathematical analysis (English: Mathematical Analysis) is the oldest and most basic branch of analytical science, which is different from the advanced mathematics content of other non-mathematics majors. Generally speaking, it refers to a relatively complete mathematics subject with the general theory of calculus, infinite series and analytic function as the main content and including its theoretical basis, and it is also a basic course for college mathematics majors.
