Figure 4

Odds ratios for EIRA and NARAC for common GVs “without zeros” ( and ). The red stars represent the expectation value of random OR (notice that is slightly different from unity due to asymmetry and discreteness of the distribution for OR); error bars show the interval that is hit by OR with randomly chosen from the interval with 95% probability; black stars display observed OR for given GV. Thus, if is above the upper error bar, the null hypothesis that the observed value of OR can arise occasionally is not supported with 5% threshold value (for the random variable ).
