Interval forecasts
WebAn interval forecast usually consists of upper and lower limits associated with a prescribed probability. The limits are sometimes called forecast limits (Wei 1990) or prediction … WebUpper/lower interval end forecasts are equivalent to: quantile forecasts at alpha = 0.5 - c/2, 0.5 + c/2 for c in coverage. """ # implement here # IMPORTANT: avoid side effects to y, X, fh, coverage # # Note: unlike in predict_interval where coverage can be float or list of float # coverage in _predict_interval is guaranteed to be a list of float
