If your ultimate goal is creating a model that will predict a future value for some dependent variable, then you need Regression Analysis. Regression Analysis is one of the most powerful statistical methods for determining the relationships between variables and using those relationships to forecast future outcomes.
Learn how to derive and implement simple and multiple linear regression models. Assess the overall quality of the models and interpret individual predictors for significance. Discover the assumptions that underlie the models and how to test whether your data meets those assumptions, and what to do when your assumptions are not met.

- Review how to use a scatter plot to determine if two variables appear correlated and to what degree.
- Explain how to calculate the correlation coefficient and the coefficient of determination.
- Show how regression analysis can be used to predict the value of one variable from another variable by fitting a least squares regression line to the data and judging the validity of the model.
- Describe how to use information generated by a computer output from a simple linear regression to write the equation of the line and perform predictions based upon the model.
- Explain the purpose of multiple regression and how it differs from simple regression.
- Describe the elements of the multiple linear regression model and identify assumptions about the data required for regression analysis to work.
- Use the “best subsets” method to determine the possible regression models and apply several techniques for selecting the best model.
- Discuss what can go wrong with multiple regression that may lead to incorrect conclusions.

WebEx – Virtual Course: Advance Preparation and Student Information
Join a Test Session
We strongly suggest that you join a WebEx test session in advance of your scheduled virtual training, using your preferred web browser. This can help prevent problems launching content the day your training begins.
If you do not have administrative privileges on the SAME computer you will be using the day of your training (i.e., your workstation within your organization) you may need the assistance of your local IT/IS help desk staff for the platform to engage correctly.
To join a test session (meeting), click here and enter your name and email address to join. If successful, you will see a screen that says "Congratulations! Your system is now set up properly ..."
Deactivate Pop-up Blockers
You should deactivate any pop-up blockers, spam filters, and company firewalls that could prevent the WebEx client platform or web-based course from working properly. Third-party toolbars such as Bing, Yahoo, and Google should also be disabled due to their own pop-up blocking capabilities.
Internet-based, self-paced training modules, which may involve combinations of text, visuals, audio, interactive simulations and quizzes (see specific courses for features and tools). These web-based courses require a computer and Internet access.
