| Subject | st: How to change the base reference variable |
| Date | Tue, 27 Nov 2012 11:57:45 +0000 (GMT) |
How do I change the "base" variable for the following when I want to compare the respondents that pay by weight against the ones that pay by flat fee. I want to use the "Flat Fee" as the base reference and compare the other values against it, so from what I understand, the Flat Fee will be 0 and the other variables relate to this one??? | Robust FOOD_REC_YESNO | Coef.
