Welcome to my homepage

I have posted here my e-book in statistical modeling. It is free for you to use, but you may not sell it, or copy without proper citation. If you want to download it to your computer, please send me an email and I will send you a compressed folder with all files. There is no cost or obligation.

To open the book click on the book icon on the menu.

The book is designed for students and practitioners who want to learn or review basic regression modeling. The book first covers some preliminary background, like hypothesis testing and confidence intervals, and then simple linear regression, multivariate linear regression, polynomial regression, and one- and two factor analysis of variance (ANOVA). I welcome your suggestions for improvements, changes and additions.

Another excellent source, which I am linking my e-book materials, is the Data Science Textbook by TIBCO. Please check that out here This was formerly the Statsoft electronic textbook.

Note, that I am in no way or form endorsing the TIBCO data science textbook. But, together these two books create a useful- and value-adding combination for both learners and practitioners.
