# How to model percentage dependent variable using logistic regression in spss

I have some aggregated data.

Indep.   Dep.    N
1.3      78%     23
1.2      67%     20


Indep var the average score of people in a particular region. Dep. var is the percent says 'yes' in that region. N is the count of subject the dep. is based on.

I have read people suggesting logistic regression to model dependent percent or proportion data, ie http://www.theanalysisfactor.com/when-dependent-variables-are-not-fit-for-glm-now-what/, I am confused as to how to do it in spss, and doesn't logistic reg requie the dep var to be binary?
