The classification accuracy score (percent classified correctly), a single-threshold scoring rule which is zero or one depending on whether the predicted probability is on the appropriate side of 0.5, is a proper scoring rule but not a strictly proper scoring rule because it is optimized (in expectation) not only by predicting … Visa mer In decision theory, a scoring rule provides a summary measure for the evaluation of probabilistic predictions or forecasts. It is applicable to tasks in which predictions assign probabilities to events, i.e. one issues a probability … Visa mer Given a sample $${\displaystyle y_{i},i=1\ldots n}$$ and corresponding forecasts $${\displaystyle F_{i}}$$ or Visa mer There are an infinite number of scoring rules, including entire parameterized families of strictly proper scoring rules. The ones shown below are simply popular examples. Visa mer • Coherence • Decision rule Visa mer Consider a sample space $${\displaystyle \Omega }$$, a σ-algebra $${\displaystyle {\mathcal {A}}}$$ of subsets of Probabilistic forecast Visa mer An example of probabilistic forecasting is in meteorology where a weather forecaster may give the probability of rain on the next day.
