Abstract:Based on the definition of rare events to be given and the assessment of the successful parameters forecasting rare events,an equation by parament transformation was suggested.It can be seen that a method to improve the forecast accuracy of rare events is to turn the rare eveuts from very little probability into large probability by conditional probability.
