In this chapter you'll be introduced to the ideas of correlation and autocorrelation for time series. Correlation describes the relationship between two time series and autocorrelation describes the relationship of a time series with its past values.

Introduction to Course

A "Thin" Application of Time Series

Merging Time Series With Different Dates

Correlation of Two Time Series

Correlation of Stocks and Bonds

Match Correlation with Regression Output

Autocorrelation

A Popular Strategy Using Autocorrelation

Are Interest Rates Autocorrelated?

Correlation and Autocorrelation

In this chapter you'll learn about some simple time series models. These include white noise and a random walk.

Autocorrelation Function

Some Simple Time Series

In this chapter you'll learn about autoregressive, or AR, models for time series. These models use past values of the series to predict the current value.

Describe AR Model

Simulate AR(1) Time Series

Compare the ACF for Several AR Time Series

Match AR Model with ACF

Estimating and Forecasting AR Model

Autoregressive (AR) Models

In this chapter you'll learn about another kind of model, the moving average, or MA, model. You will also see how to combine AR and MA models into a powerful ARMA model.

Applying an MA Model

Equivalence of AR(1) and MA(infinity)

Moving Average (MA) and ARMA Models

This chapter will show you how to model two series jointly using cointegration models. Then you'll wrap up with a case study where you look at a time series of temperature data from New York City.

From stock prices to climate data, time series data are found in a wide variety of domains, and being able to effectively work with such data is an increasingly important skill for data scientists. This course will introduce you to time series analysis in Python. After learning about what a time series is, you'll learn about several time series models ranging from autoregressive and moving average models to cointegration models. Along the way, you'll learn how to estimate, forecast, and simulate these models using statistical libraries in Python. You'll see numerous examples of how these models are used, with a particular emphasis on applications in finance.

<h2>Discover How to Use Time Series Methods </h2>
You’ll start by covering the fundamentals of time series data, as well as simple linear regression. You’ll cover concepts of correlation and autocorrelation and how they apply to time series data before exploring some simple time series models, such as white noise and a random walk. 
Next, you’ll explore how autoregressive (AR) models are used for time series data to predict current values and how moving average models can combine with AR models to produce powerful ARMA models. 
<br><br>
Finally, you’ll look at how to use cointegration models to model two series jointly before looking at a real-life case study. 
<br><br>
</h2>Explore Python Models and Libraries for Time Series Analysis</h2>
By the end of this course, you’ll understand how time series analysis in Python works. You’ll know about some of the models, methods, and libraries that can assist you with the process and will know how to choose the appropriate ones for your own analysis.
