計(jì)算比率的幾何平均數(shù)時(shí),元素存在負(fù)數(shù)時(shí)怎么辦?比如我計(jì)算五年的,這五年的數(shù)里出現(xiàn)了三個(gè)負(fù)數(shù),怎么辦?

負(fù)數(shù)不影響的,負(fù)數(shù)就是減少

當(dāng)原始數(shù)出現(xiàn)有負(fù)數(shù)幾何增長率就得不出結(jié)果

2016年增長率為-42.15%,2017年增長率為-439.02%,2018年為342.68%,2019年為36.96%,2020年為0.27%,請(qǐng)問問它的幾何平均年增長率是多少,公式是如何,謝謝
