 5 | 3 Days, 20+ AI Experts, 25+ Workshops and Power Talks 6 | 7 | Code: USD75OFF 8 | 9 | 10 | 11 | 12 | # Data Forecasting and Segmentation Using Microsoft Excel 13 | 14 | Data Forecasting and Segmentation Using Microsoft Excel 15 | 16 | This is the code repository for [Data Forecasting and Segmentation Using Microsoft Excel](https://www.packtpub.com/product/data-forecasting-and-segmentation-using-microsoft-excel/9781803247731), published by Packt. 17 | 18 | **Learn how to design and build cloud-based data transformation pipelines using AWS** 19 | 20 | ## What is this book about? 21 | 22 | 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. 23 | 24 | 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. 25 | 26 | 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. 27 | 28 | This book covers the following exciting features: 29 | * Understand why machine learning is important for classifying data segmentation 30 | * Focus on basic statistics tests for regression variable dependency 31 | * Test time series autocorrelation to build a useful forecast 32 | * Use Excel add-ins to run K-means without programming 33 | * Analyze segment outliers for possible data anomalies and fraud 34 | * Build, train, and validate multiple regression models and time series forecasts 35 | 36 | If you feel this book is for you, get your [copy](https://www.amazon.in/Forecasting-Segmentation-Using-Microsoft-Excel/dp/1803247738/ref=sr_1_1?crid=21VSJWCRJ0ZXJ&keywords=Data+Forecasting+and+Segmentation+Using+Microsoft+Excel&qid=1654770945&sprefix=data+forecasting+and+segmentation+using+microsoft+excel+%2Caps%2C214&sr=8-1) today! 37 | 38 | https://www.packtpub.com/ 39 | 40 | ## Instructions and Navigations 41 | All of the code is organized into folders. 42 | 43 | The code will look like the following: 44 | ``` 45 | le = LabelEncoder() 46 | for i in bin _ cols: 47 | churn _ data[i] = le.fit _ transform(churn _ data[i]) 48 | ``` 49 | 50 | **Following is what you need for this book:** 51 | This book is for data and business analysts as well as data science professionals. MIS, finance, and auditing professionals working with MS Excel will also find this book beneficial. 52 | 53 | With the following software and hardware list you can run all code files present in the book (Chapter 1-13). 54 | 55 | ### Software and Hardware List 56 | 57 | | Chapter | Software required | OS required | 58 | | -------- | -------------------------------------------------------------------------------------| -----------------------------------| 59 | | 1-13 | Microsoft Excel | Any OS | 60 | | 1-13 | Jupyter notebook environment | Any OS | 61 | 62 | We also provide a PDF file that has color images of the screenshots/diagrams used in this book.

In his work, Fernando applies Python k-means and time series machine learning algorithms, using Normalized Difference Vegetation Index (NDVI) drone images to find crop regions with more resilience to droughts. He also applies time series and k-means algorithms for supply chain management (logistics) and inventory planning for seasonal demand. 71 | ### Download a free PDF 72 | 73 | If you have already purchased a print or Kindle version of this book, you can get a DRM-free PDF version at no cost.
