Abstract

CHRISTOF(I,P) returns the likelihood ratio test values for the unconditional coverage, independence and conditional coverage tests, respectively, for a binary time series I and a coverage probability P. The series I(t) is defined as: I(t) = 1 if the actual value of the forecasted process belongs to the prediction interval for time t computed at time t-1 and 0 otherwise. [LR_UC,LR_I,LR_CC,LR_UC_P,LR_I_P,LR_CC_P]=CHRISTOF(I,P) additionally returns the corresponding p-values.
