在NBA球员的技术统计中有“EFF”一项,一般译作“效率”,是指球员的得分、篮板、助攻、抢断、盖帽五大技术统计之和减去投篮不中次数和罚球不中次数,再减去失误次数后得出的一个综合指数。但这种算法的缺陷是显而易见的。它的基本意图是用球员在场上做的“有用功”减去“无用功”,但是在计算“有用功”的时候把篮板、助攻等项都计算在内,而在计算“无用功”的时候却只是减去了和得分有关的两项——为什么不再减去抢篮板没有抢到的,抢断没有断到的,盖帽没有盖到的?且不考虑出场时间、犯规等影响,它最大的问题是既把 In the technical statistics of NBA players, there is “EFF”, which is generally translated as “efficiency” and refers to the sum of the five technical statistics of a player’s score, rebounding, assists, steals and blocks minus the number of shots missed and the number of free throw attempts, Minus the number of mistakes made after a composite index.

Its basic intent is to subtract “useless” from the “useful work” the player performs in the field, but to count rebounds and assists when calculating “useful work,” while calculating “useless” Just minus the two points and scoring - why no longer minus the rebound did not get, steals did not break, the cap did not cover? And does not consider playing time, foul and other effects, its biggest problem It is both
