Browser calculator · French and English
Compare a forecast with persistence, NICE
Paste observations and forecasts, choose a horizon, read absolute errors and NICE ratios.
Interactive tools: choose a question, explore a method
Calculators, teaching experiments and research applications, organized by domain and language.
Start with an example, change an input and examine what changes. Research calculators and medical applications are for research and education; their assumptions and limitations are stated in the linked pages.
Languages: the seven technical calculators have French and English interfaces. The course tools (ROC, normal distribution, regression, attenuation, cooling, freezing, COP) are in French. Dedicated applications and the comparison tool retain their existing interfaces; filter by language before opening a tool.
