N-test for 365 forecasts of three trials by the LN-Bayes model. The black curve indicates the theoretical distribution of the frequency of qualifying events calculated from forecast probabilities, and the vertical dashed line indicates the observed frequency of qualifying events. Ns is the number of forecast sequences and Nq is the number of sequences filled with qualifying event in the forecast period.
