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.

Part 2 – Grouping Data to Find Segments and Outliers
Part 3 – Simple and Multiple Linear Regression Analysis
Part 4 – Predicting Values with Time Series


Here are the answers to the preceding questions:

  1. Because we can visualize the possible outliers and the value range that is outside of the normal behavior of the data.
  2. Identify the group with different behavior in one of the variables of the dataset using pivot tables. Explore whether this same group has suspicious behavior compared to the rest of the variables analyzed.
  3. No, the most important factor is BMI. Age is not relevant for the number of complaints to the insurance company.
  4. High duration of a medium number of packets.
  5. The variable used was the money expended. The outlier was confirmed by the V1 variable.
