@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

@nataliemj10 @gelliottmorris I know I can sound grumpy about this stuff at times. But I've also spent A LOT of time thinking about these issues over MANY election cycles and tried out a lot of strategies that did or didn't work. So it's coming from a place of practical experience. — PolitiTweet.org

@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
