| Summary, etc. |
DESCRIPTION<br/>The book provides nine tutorials on optimization, machine learning, data mining, and forecasting all within the confines of a spreadsheet. Each tutorial uses a real-world problem and the author guides the reader using query’s the reader might ask as how to craft a solution using the correct data science technique. Hosting these nine spreadsheets for download will be necessary so that the reader can work the problems along with the book.<br/><br/>Important topics covered by the book:<br/><br/>Linear and integer programming<br/>K-nearest neighbors graphs and clustering<br/>Logistic regression<br/>Demand forecasting with seasonal adjustments<br/>Price sensitivity, revenue optimization, and price-sensitive forecasting<br/>Naïve Bayes classification<br/>Outlier detection using graphs and Local Outlier Factors<br/>Multi-criteria decision analysis |
