Hi,

While writing an essay on transitions to democracy in SSA mainly using logit models for survival and emergence I included a standard regression in the appendix to just further a small point. My question regards the use of this regression. So I have data from 43 countries in SSA over the years from 1960-2016, looking at the effect of several independent variables on polity2's 20 point scale for levels of democracy. I have read that using standard regression is not allowed. I've looked it up but struggle to find explicit statistical details for why I can't run regression on cross-sectional/time-series data. As an undergraduate I would appreciate any advice possible.

Many thanks, Charlie
