regression works only when ur independent variables are all

quantitative; you need to convert ur problem to one with quantitative

indep variables by defining dummy variable feedback1 (= 1 iff feedback

=1); feedback2 (= 1 iff feedback = 2); if you are including a constant

in your model (as indep. variable) DON'T define feedback3, otherwise

your data will be perfectly multicollinear:

feedback1+feedback2+feedback3 = 1 (constant); if you are not including

a constant, INCLUDE feeback3 in the model.
