I've been asked to build a predictive model with data that includes both continuous and class variables. Some of the class variables are ordinal in nature (essentially self-reported rankings of various things). I'm playing around with both Proc Genmod and Proc Adaptivereg as ways to build my model. How do I specify which ones of my class variables are ordinal? Do I have to code them in a certain way for this to be true?
ANOVA, or Analysis Of Variance, is used to compare the averages or means of two or more populations to better understand how they differ. Watch this tutorial for more.
