In fact, I have found a journal article that used multiple regression on using Likert scale data. Based upon this threshold, the obtained estimated probability is classified into classes. The dependent variable used in this document will be the fear of crime, with values of: 1 = not at all fearful Use OLS regression anyway • Commonly done; but can give incorrect results • Possibly check robustness by varying coding of interval between outcomes – 2. In general, a binary logistic regression describes the relationship between the dependent binary variable and one or more independent variable/s.. Ordinal logistic regression is used when the categories have a specific hierarchy (like class year: Freshman, Sophomore, Junior, Senior; or a 7-point rating scale from strongly disagree to strongly agree).
