Overview of this book

This book will take you on a practical journey, teaching you how to implement solutions for many use cases involving time series analysis techniques. This learning journey is organized in a crescendo of difficulty, starting from the easiest yet effective techniques applied to weather forecasting, then introducing ARIMA and its variations, moving on to machine learning for audio signal classification, training deep learning architectures to predict glucose levels and electrical energy demand, and ending with an approach to anomaly detection in IoT. There’s no time series analysis book without a solution for stock price predictions and you’ll find this use case at the end of the book, together with a few more demand prediction use cases that rely on the integration of KNIME Analytics Platform and other external tools. By the end of this time series book, you’ll have learned about popular time series analysis techniques and algorithms, KNIME Analytics Platform, its time series extension, and how to apply both to common use cases.

Introducing the (S)ARIMA models

With our little recap of regression taken care of, we can start talking about the requirements and different components of the ARIMA and SARIMA models, including how they’re the same and how they’re different. However, before we get into the formula and the two variations on the regression that make up the (S)ARIMA model, let’s cover some of its requirements.

Requirements of the (S)ARIMA model

While the (S)ARIMA model is famously an effective option for forecasting time series data and requires far less data than many alternative approaches, it does come with a little baggage. Unlike the techniques we’d likely bucket into the Machine Learning category, such as neural networks or even regression forests, the (S)ARIMA model requires a few things for our underlying data distribution, namely that our data is stationary. Let’s dive into this topic a bit more.

What is stationarity?
