# Introduction to Time series analysis

This section introduces time series analysis in general. This should be considered as guidance notes for the time series analysis assignment help and time series analysis homework help sections on time series analysis.

In a time, series analysis, a series of data points are indexed, listed or graphed in the order of time. For simple understanding, a time series is a sequence which records data points over successive equally spaced points in time. It is a sequence of discrete data over time. Some examples of time series are the height of tides in the ocean, the count of sunspots, and the daily closing value of the S&P 500 index.

A time series analysis is frequently plotted using line charts. Time series analysis has a wide range of applications. Not only are they used in statistics but also in pattern recognition, econometrics, financial analysis, weather forecasts and trajectory forecasting, Other applications also include predicting earthquakes, electroencephalography, engineering, astronomy, and communications. Time series analysis is largely used in the domains of applied sciences and engineering. The real life applications are very important topics under the time series analysis assignment help and time series analysis homework help section.

Time series analysis is comprised of different methods to analyze the time series data. Using time series analysis, we can easily extract meaningful statistics and also observe other characteristics of the data set. Time series forecasting is used in many models to predict the future values solely based on the previously observed values. Many times, regression analysis is employed in a way that it test different theories. These theories state that the current values of one or more independent time series affect the current value of another time series. However, this type of analysis cannot be termed as time series analysis.

## Properties of Time series analysis

The properties of time series analysis explanation are written in sync with the time series analysis assignment help and time series analysis homework help sections. This section discusses the distinct properties of time series analysis.

- As a statistical tool, time series analysis allows comparing values of a single time series. It can also aid analysis of multiple dependent time series at different points in time.
- Time series data is chronologically ordered. Because of this, time series analysis is distinct from other cross-sectional studies. In cross-sectional studies, there is no natural ordering of the observations in the data set. Time series analysis is also distinct in a sense that, where the observations particularly relate to geographical locations.
- time series will generally point out the fact that observations close to each other in time will be more closely related than other observations that are further apart.
- In addition, time series models generally make use of the natural one-way ordering of time. This allows the values for the given period to be expressed as derived in some way from historical values, instead of the future values.
- Time series analysis can be applied different data types. It can be used in continuous data distribution, discrete data distribution or a discrete symbolic data distribution.

### Methods for analysis

Methods for time series analysis can be classified into two terms: frequency-domain methods and time-domain methods. There are two other alternative methods of time series analysis. The first of the two terms are linear and nonlinear analysis. The second is the univariate and multivariate analysis.
