The other is the Indifference Principle of Trial Setup, with which the Theorem of Opinions' Convergence in the subjective probability theory is justified.
二是“試驗機制無差别原則”,用以為主觀主義概率歸納邏輯的意見收斂定理進行辯護。
The language of uncertainty has three main categories: (1) words such as probably, possibly, surely, which denote a single subjective probability and are potentially quantifiable;
模糊語言有三大類:(1)“很可能”、“有可能”、“肯定會”之類的詞。這類詞表示個人主觀認為的可能性,這些詞在發言人的心目中是有一定的潛在的數量的;
There has been four kinds of main early warning models of exchange crisis at present, namely signal approach, probit model, cross-county regression model and subjective probability method.
目前已經出現了四種主要的外彙危機預警模型,即信號方法、概率單位方法、截面回歸方法以及主觀概率法。
The solution of Hume's problem by the subjective or personalistic theory of probability induction relies heavily on Dutch Book theorem, which is divided into two parts, static and dynamic.
當代概率歸納邏輯的一個重要學派即主觀主義或私人主義對待休谟問亦即歸納合理性問題的态度,密切地依賴于他們提出的大棄賭定理。
The probability of nuclear attack in some major cities is not very great in a subjective sense, but it is by no means zero.
從主觀上講,今後發生核打擊的可能性不太大,但也不是完全沒有。
主觀概率(Subjective Probability) 是指個體基于自身知識、經驗、信念以及對事件的理解,對某一事件發生的可能性所賦予的數值度量。它與經典概率(基于長期重複試驗的頻率)不同,強調判斷者的個人視角和信息狀态,是貝葉斯統計學和決策理論的核心概念。其核心特征包括:
主觀概率是量化個人信念和不确定性的工具,其核心在于依賴個體信息與判斷,具有可更新性(貝葉斯更新)和個體差異性。它在處理信息不完全、事件不可重複或獨特情境下的決策問題中尤為重要,是連接個體認知與理性決策的橋梁。
主觀概率(Subjective Probability)是指基于個人信念、經驗或直覺對某一事件發生可能性的量化判斷,而非依賴客觀數據或長期頻率。以下是詳細解釋:
主觀概率反映了個體對不确定事件的主觀信心程度。例如,投資者可能認為某股票上漲的概率為70%,這并非基于曆史數據,而是綜合了市場趨勢、公司新聞等個人判斷。
總結來看,主觀概率是處理不确定性的重要工具,尤其在信息有限時,但需注意其主觀性可能帶來的局限性。
