面向人工智能与金融模型风险的概率与统计

Probability and statistics underpin financial models: estimating default and claim rates, testing calibration, measuring discrimination and detecting drift. On this platform they supply the measures and tests that show whether a model is performing as intended.

What probability and statistics does here.

Probability and statistics provide the mathematical framework for describing uncertainty and learning from data. They underpin estimation, testing and prediction in every risk discipline. In artificial intelligence and financial stability, statistical methods quantify the likelihood and uncertainty of losses across interconnected 系统. They make the evidence behind risk decisions explicit and reproducible. The canonical description is on STEM Commons.

Calibration testing

Predicted default or claim probabilities are compared with observed rates by band, using binomial and other tests suited to the sample size.

Drift statistics

Population stability and distribution distance measures are computed between periods to detect shifts in model inputs and scores.

Group outcome comparison

Outcome and error rates are compared across groups with confidence intervals, so differences are not read from noise.

06验证

结果如何核查。

Results are checked through diagnostics, cross-validation and sensitivity to assumptions. Independent replication confirms findings.

核查如何开展
Sample sizeTests state power and minimum sample sizes
Multiple testingMany simultaneous tests are corrected for chance findings
Out-of-samplePerformance is reported on data not used for fitting

Inference depends on assumptions about independence, distribution and sampling that may not hold. Small or biased samples limit reliability.

08管理责任
