As an example. I used a panel company for more than half of the survey response and the balance came from client marketing efforts. I would like to do a crosstab comparing those two sources. I have a pid variable and if it is blank, that means the response came from client marketing. If it has a value, I know it it is panel. I would like my banner points to be CLIENT and PANEL.
All the data is in so I would be creating new variables. I would like to do similar exercises based on zip code, county of residence (collapsing several into one point), and others.
Any suggestions or documentation that might help me with this?
