Cover Story: O-information is an information-theoretic measure based on composite Shannon entropy measures that quantifies the balance between redundancy and synergy in systems of variables. However, estimations of O-information for discrete variables suffer from bias, which has not yet been fully addressed. This study investigates how sample size and the number of bins influence bias in O-information estimation. The results reveal that a small ratio of sample size to the number of bins causes a strong bias toward synergy in independent systems. Independent systems may thus potentially be falsely classified as synergistic. A bias correction method is proposed, offering partial improvement. Nonetheless, simulations of independent systems are needed to better understand and benchmark this bias. View this paper
