Notes on the model
Questions are open to interpretation. How does one determine if someone has “It-Factor,” for example? This will inevitably yield individual bias - however, this is true of any predictive model.
In the case of multi-way races, you must do each candidate head-to-head to get an accurate result, as there is no built-in function for this right now. I encourage putting those head to head results in a Bradley-Terry model for an accurate analysis.
