Overview of this book

We start with the perplexing task of extracting value from huge amounts of barely intelligible data. The data takes a convoluted route just to be on the servers for analysis, but insights can emerge through visualization and statistical modeling techniques. You will learn to extract value from IoT big data using multiple analytic techniques. Next we review how IoT devices generate data and how the information travels over networks. You’ll get to know strategies to collect and store the data to optimize the potential for analytics, and strategies to handle data quality concerns. Cloud resources are a great match for IoT analytics, so Amazon Web Services, Microsoft Azure, and PTC ThingWorx are reviewed in detail next. Geospatial analytics is then introduced as a way to leverage location information. Combining IoT data with environmental data is also discussed as a way to enhance predictive capability. We’ll also review the economics of IoT analytics and you’ll discover ways to optimize business value. By the end of the book, you’ll know how to handle scale for both data storage and analytics, how Apache Spark can be leveraged to handle scalability, and how R and Python can be used for analytic modeling.

Preface

Forecasting using ARIMA


Sometimes, you will have the need to forecast future values of a time series. For example, this could be a requirement to estimate the next several months of active IoT devices; or, it could be a need to project the usage hours of remote oil well pumps. One of the most popular methods to forecast time series is AutoRegressive Integrated Moving Average (ARIMA).

ARIMA is not one model but a collection of related methods that attempt to describe autocorrelations in the data in order to forecast future values. ARIMA is a combination of moving average and autoregressive techniques. Autoregressive means that the forecasting of future values of a variable is based on the linear combination of the past values of variables.

ARIMA incorporates both trend and seasonality effects into future forecasts. It can model both seasonal and nonseasonal data with a range of methods.

Using R to forecast time series IoT data

The forecast package contains ARIMA functions in R. You can install...
