آ آ آ آ آ آ آ آ This is todayâ€™s most complete guide to regression analysis with Microsoftآ® Excel for any business analytics or research task.
Drawing on 25 years of advanced statistical experience, Microsoft MVP Conrad Carlberg shows how to use Excelâ€™s regression-related worksheet functions to perform a wide spectrum of practical analyses.
Carlberg clearly explains all the theory youâ€™ll need to avoid mistakes, understand what your regressions are really doing, and evaluate analyses performed by others.
From simple correlations and t-tests through multiple analysis of covariance, Carlberg offers hands-on, step-by-step walkthroughs using meaningful examples.
آ He discusses the consequences of using each option and argument, points out idiosyncrasies and controversies associated with Excelâ€™s regression functions, and shows how to use them reliably in fields ranging from medical research to financial analysis to operations.
آ You donâ€™t need expensive software or a doctorate in statistics to work with regression analyses.
Microsoft Excel has all the tools you needâ€”and this book has all the knowledge! آ Understand what regression analysis can and canâ€™t do, and why Master regression-based functions built into all recent versions of Excel Work with correlation and simple regression Make the most of Excelâ€™s improved LINEST() function Plan and perform multiple regression Distinguish the assumptions that matter from the ones that donâ€™t Extend your analysis options by using regression instead of traditional analysis of variance Add covariates to your analysis to reduce bias and increase statistical power آ .
