prior probability

基本解釋

Secondly, it is unneeded to obtain the prior probability in course of rough sets theory application.
而且，應用粗糙集理論不需要事先確定事件的先驗概率。
First, the occurrence of all the system states is considered to have an equal possibility and for each component in the diagnosis system set a prior probability.
該模型首先假設系統(tǒng)的所有狀態(tài)都是可能發(fā)生的，并對系統(tǒng)中的各個元件設定一個先驗概率。
It collects information by market investigation, amends the prior probability, and consequently increases assurance of the investor on future success, so that the risk of decision-making is reduced.
它通過市場調(diào)查增加信息量，對先驗概率進行修正，從而提高決策者對未來可能性的把握，達到降低決策風險的目的。
