1. Time Series: Let's Start

Start from the introduction to time series to move on to more in-depth topics. Find out what it is, how often time series occur in real business, how to analyze them and make forecasts.

Practical Examples

Implementation in Python

2. Time Series Processing

What is the difference between trend and seasonality? Is the data I'm working with stationary or not? In this section, you will learn how to analyze characteristics of time series using Python!

Reading and Visualizing Data

Autocorrelation

3. Time Series Visualization

Learn more about time series through… their visualization! Explore your data with 2D and 3D graphs.

4. Stationary Models

What will be our first step? Let's start with stationary models! Create your first predictive model that will forecast time series.

Examples of Stationary Time Series

Simple Moving Average

Autoregressive-Integrated-Moving-Average Model

5. Non-Stationary Models

Most of the data you work with is non-stationary. Learn how to process such data and what models to use to predict it.

Examples of Non-Stationary Time Series

Convert Non-Stationary Data to Stationary

Financial Markets

The drive to predict the stock market probably started at the same time as the stock market itself. But as you already know, now we can realize this "dream" with the help of predictive models.

Datasets with stock market records imply an analysis of trends, cyclical fluctuations, and seasonality. For example, stock markets tend to perform well at the start of the year, as that is when many investors have fresh capital. Share prices may rise ahead of long weekends and three-day holidays. This is due solely to human factors.

Basically, to predict the stock of the market, models are used that work with data that has multiple seasonality. One of the most popular models is Prophet, which was created by Meta. The mathematical model looks like this:

The equation includes the parameters of trends g(t), seasonality s(t), holidays h(t) and noise e(t)

You can experiment with the model in Python:

Everything was clear?
