True Skill Statistic: The Importance of Proper Calibration in Predictive Modeling

True skill statistic (TSS) is a method used to measure the predictive accuracy of various models. It provides a standardized framework for assessing different approaches to prediction problems. When evaluating the ability of a model to make accurate predictions, TSS can help determine whether the model is better than chance alone and identify areas where improvements can be made. This article discusses the importance of true skill statistic and its applications across various fields.

What is True Skill Statistic?

True skill statistic is a measure used to assess the performance of predictive models by comparing their predictions against those generated by random guessing. It was developed to provide a standardized way to evaluate different prediction strategies and compare them with one another. The calculation of TSS involves dividing the area under the learning curve into three regions: one for being above all other competitors, one for being worse than others, and one for being within the range of competitors. TSS is calculated using the following formula:
