Regression coefficients of two models on the politial representation of women in national legislatures. The blue dots and lines correspond to a model that uses a dependent variable catering for the proportion of women in the population; the red dots and lines correspond to a model that uses the proportion of women in national legislatures as dependent variable. Otherwise the models are the same. Results from using beta regressions are available here: http://druedin.com/2013/08/09/women-in-national-legislatures/
