Abstract: So you have missing data... how do you fix it? If you're asking this question, you're well aware of the fact that missing data plagues nearly every data set. Whether missing values are represented by blanks, NAs, or -999, they're everywhere and need to be handled. The most common approaches are to ignore or drop the missing data, but these result in a lot of negative consequences. A slightly more sophisticated approach is to fill the missing data in with some value, but also this has a lot of negative and unintended side effects. We'll cover why these methods are subpar and how to properly handle missing values. The goal is for you to walk away with a solid, intuitive understanding of how to handle missing data and some of the practical tips for how you can implement these techniques in a real setting.
