Ordinal Predictors in Linear Regression [Ordinal Independent Variables]

How can you include an ordinal independent variable in linear regression analysis?

An ordinal predictor regression can be implemented in different ways. There are rather simple and easy to implement techniques and very advanced approaches to include ordinal independent variables in regression models.

This video tutorial is going to show you some basic techniques you could easily implement for treating ordinal independent variables in regressions in order to write your bachelor's thesis or master's thesis.

In addition, this video will provide you with literature references for more advanced methods for dealing with ordinal predictors in regression if you decide to use more sophisticated (and much more difficult) techniques.
