@gelliottmorris @nataliemj10 With small sample sizes and highly correlated variables, it is VERY hard to determine empirically which ones are most important, so it is usually a better strategy to create an index. — PolitiTweet.org

@gelliottmorris @nataliemj10 The strategy is that you decide in advance which variables to include based on their real-world significance. And then just see how well they do. That is a good way to avoid p-hacking or overfitting. — PolitiTweet.org

@gelliottmorris @nataliemj10 On the contrary, it's much better to decide on your hypothesis ahead of time, rather than to test multitudes of hypotheses on small, noisy datasets with high covariance. Will yield much more honest assessments of uncertainty that won't deteriorate much in-sample to out-of-sample. — PolitiTweet.org
