What are the several methods of applying time series analysis?

Time series analysis (Timeseriesanalysis) is a statistical method for dynamic data processing. The method is based on the theory of stochastic processes and methods of mathematical statistics, the study of random data series obeyed by the statistical laws, in order to be used to solve practical problems.

Introduction

It includes general statistical analysis (e.g., autocorrelation analysis, spectral analysis, etc.), statistical modeling and inference, as well as optimal prediction, control and filtering of time series. Classical statistical analysis assumes that data series are independent, while time series analysis focuses on the interdependence of data series. The latter is actually a statistical analysis of the stochastic process of discrete indicators, so it can also be regarded as a component of stochastic process statistics. For example, the rainfall of the first month, the second month,……, and the Nth month of a certain region is recorded, and the rainfall of the future months can be forecasted by using the time series analysis method.

With the development of computer-related software, mathematical knowledge is no longer an empty theory, time series analysis is mainly based on mathematical statistics and other knowledge, the application of relevant mathematical and scientific knowledge in the relevant aspects of the application and so on.

Components

A time series is usually composed of four elements: trend, seasonal variation, cyclical fluctuations and irregular fluctuations.

Trend: is a time series over a long period of time to show a continuous upward or continuous downward movement.

Seasonal variations: are cyclical fluctuations in the time series that are repeated within a year. It is the result of the influence of various factors such as climatic conditions, production conditions, holidays or people’s customs.

Cyclical fluctuations: is the time series show a non-fixed length of the cycle. Cyclic fluctuations of the cycle may last for a period of time, but unlike the trend, it is not a continuous change in a single direction, but the same rise and fall of the alternating fluctuations.

Irregular fluctuations: are random fluctuations in a time series after the trend, seasonal variations and cyclical fluctuations are removed. Irregular fluctuations are usually always mixed in the time series, resulting in a time series to produce a wavy or oscillating movements. A series that contains only random fluctuations is also called a smooth series.

Basic Steps

The basic steps of time series modeling are:

①Observation, survey, statistics, sampling and other methods to obtain the observed system time series dynamic data.

② According to the dynamic data for the correlation diagram, correlation analysis, autocorrelation function. Correlation charts can show the trend of change and cycle, and can find the jump point and inflection point. A jump point is an observation that is inconsistent with other data. If the jump points are correct observations, they should be taken into account in modeling, and if they are anomalies, the jump points should be adjusted to the desired values. An inflection point, on the other hand, is a point at which a time series suddenly changes from an upward trend to a downward trend. If there is an inflection point, the time series must be modeled with a different model to fit the time series, such as the use of threshold regression model.

3) Identify a suitable stochastic model for curve fitting, i.e., use a generalized stochastic model to fit the observed data of the time series. For short or simple time series, trend models and seasonal models with errors can be used for fitting. For smooth time series, the generalized ARMA model (autoregressive sliding average model) and its special case autoregressive model, sliding average model or combined-ARMA model can be used to fit. The ARMA model is generally used when there are more than 50 observations. For non-stationary time series, the observed time series should be first differentiated into a stationary time series, and then the appropriate model should be used to fit this differentiated series.

Main Uses

System Description

An objective description of a system based on time series data from observations of the system using curve fitting.

System analysis

When observations are taken from more than two variables, the changes in one time series can be used to explain the changes in the other time series, thus providing insight into the mechanism of a given time series.

Forecasting the Future

The ARMA model is generally used to fit a time series and predict the future values of that time series.

Decision making and control

Based on the time series model, the input variables can be adjusted to keep the system development process on target, i.e., necessary controls can be made when the process is predicted to deviate from the target.

Steps in Time Series Analysis

Time series analysis is a statistical technique used to predict future values, mainly by observing and studying the trends and patterns of data over time. The steps in time series analysis include data collection, data visualization and correlation analysis, model selection and fitting.

1, data collection:

First, the time series dynamic data of the observed system is obtained through observation, survey, statistics and sampling. This is the basis of the whole analysis process, the quality and accuracy of the data has a direct impact on the analysis results.

2, data visualization and correlation analysis:

Collected dynamic data will be plotted into a correlation diagram, correlation analysis, and derive the autocorrelation function. The correlation graph can visualize the trend and cycle of data changes, and also can find the jump point and inflection point.

The jump point is an observation that is inconsistent with other data. If the jump point is a correct observation, it should be taken into account in modeling, and if it is an anomaly, the jump point should be adjusted to the desired value. The inflection point, on the other hand, is the point at which the time series suddenly changes from an upward trend to a downward trend. If there is an inflection point, a different model must be used to fit the time series in segments when modeling.

3. Model Selection and Fitting:

Based on the second step, a suitable stochastic model is selected for curve fitting, i.e., a generalized stochastic model is used to fit the observed data of the time series.

For short or simple time series, trend and seasonal models plus errors can be used for fitting. For smooth time series, a generalized ARMA model (autoregressive sliding average model) and its special cases such as autoregressive model, sliding average model, or combined ARMA model can be used for fitting.

The ARMA model is generally used when there are more than 50 observations. For non-stationary time series, it is necessary to carry out the difference operation first, to be transformed into a stationary time series, and then use the appropriate model to fit this difference series.

The above are the basic steps of time series analysis, each step has its own unique role, one without the other. Through these steps, we can effectively analyze and forecast time series data to provide strong support for decision-making.
