Logistic regression - Wikipedia
Webvalues from an OLS regression can never be guaranteed to lie in the unit interval. Thus, the drawbacks of linear models for fractional data are analogous to the drawbacks of the linear probability model for binary data. The most common alternative to equation (1) has been to model the log-odds ratio as a linear function.
