Help with survey data:

Hello R colleagues,

I hope this is an appropriate place to direct this question. It
relates specifically to the comparability of a 5-point likert to a 4-
point likert scale.

Two ways come to mind: one is to collapse both into a dichotomous
variable and do a logistic regression on both. The danger here is that
I have to decide what to do with the middle position in the first
question, assign it to the egalitarian or non-egalitarian category.
A second way would be to multiply the scores in the first question by
4 (to get results that are either 4, 8, 12, 16 or 20) and then
multiply the second question by five to get responses that are either
5, 10, 15 or 20. My idea is then to add the two, average them and use
that value as an index of economic egalitarianism?
Yes / no? Suggestions?

I am an R user and I hope that a purely statistical question is not
especially misplaced.

Yours truly,

Simon Kiss
