First, the new contingent try subdivided on the an surpass subset, that contains businesses that have confident chance-adjusted efficiency (since the were chosen for Profile dos), and a keen underperform subset. The brand new positivity rating is calculated by using equation 3,
where ???????? is the positivity get from token ??; ???? ???????????????????? (???? ???????????????????????? ) is the amount of biographies regarding outperform (underperform) subset containing token ??; and ?? ?????????????????? podpora maiotaku??
