She found a decreasing convex exponential model and a decreasing convex quadratic model. So which of the following functions better fits the data? So, function A, this is an exponential, this is the one in green right over here, and function B, this one right over here is a quadratic, and you can see this one in purple. And so, which one of those better fits the data? And so, if we look at what's going on here, the green function, the exponential one, most of the data points for any given duration, for how long the title's been out, it looks like it's consistently underestimating. That it's always, you know, it's the model's guess or what the model would say the price is, is always, at least for, except for only, essentially except for only one data point right over here, for all of these other data points, it's underestimating what the price would be. The purple model, or the purple function right over here, it is, it has more of a balance between overestimating right over here, and so it's overestimating by a little bit, and underestimating, and its underestimates are closer, and its overestimates are closer than this green model.
