WebBy Joannès Vermorel, February 2012. The pinball loss function, also referred to as the quantile loss, is a metric used to assess the accuracy of a quantile forecast. Evaluating the accuracy of a quantile forecast is a subtle problem. Indeed, contrary to the classic forecasts where the goal is to have the forecast as close as possible from the ... WebJul 29, 2024 · If you scale both actuals and (roughly) predictions by a factor of 100, the difference is also scaled by 100, so the square of the difference is scaled by 10,000. It works out. The features don't have anything to do with this effect. If the MSE is a metric that is to be used on a relative scale, how do I interpret it?
