RR(Risk Ratio):风险比,也称为相对风险(Relative Risk),用于比较两组人群中患病或经历某一事件的风险。它是两组中患病风险的比值,通常用于疫情研究和临床试验中。 公式:RR = (A / (A + B)) / (C / (C + D)) OR(Odds Ratio):概率比,用于描述两组中某一事件发生的几率之比。OR通常用于回顾性研究...

An open-loop transfer function is used for the bode stability criterion due to its less frequency response than one amplitude ratio for all frequencies. Thus, this isan overview of the Bode Plot, its working, and its applications. A Bode plot is a frequency response plot including two graphs...
