Data Forecasting and Segmentation Using Microsoft Excel

By: Fernando Roque

Overview of this book

Data Forecasting and Segmentation Using Microsoft Excel guides you through basic statistics to test whether your data can be used to perform regression predictions and time series forecasts. The exercises covered in this book use real-life data from Kaggle, such as demand for seasonal air tickets and credit card fraud detection. You’ll learn how to apply the grouping K-means algorithm, which helps you find segments of your data that are impossible to see with other analyses, such as business intelligence (BI) and pivot analysis. By analyzing groups returned by K-means, you’ll be able to detect outliers that could indicate possible fraud or a bad function in network packets. By the end of this Microsoft Excel book, you’ll be able to use the classification algorithm to group data with different variables. You’ll also be able to train linear and time series models to perform predictions and forecasts based on past data.

Summary

In this chapter, we applied our knowledge of grouping statistics to three of the most used Kaggle datasets. We learned that credit card transaction fraud could be analyzed by amounts that are out of the scope of regular transaction money payments. The K-means grouping algorithm can be applied to find out what the quantity and duration of the packets in login attempts are to find out whether there is suspicious login activity or not. Finally, the K-means function can help to conclude that age is not an important factor for money complaints. It is more important to keep the BMI under low-risk levels than the age of an insurance company's clients.

In the next chapter, we are going to build a prediction model based on the possible relationship between two variables.
