LZ原话是“谁能把概率这个最基本的概念讲清楚”
我想老师都会有普遍性的解释过这个概念,而楼主问这个问题有点太独立化。
本来概率和统计是密不可分的:
Frequentists talk about probabilities only when dealing with experiments that are random and well-defined. The probability of a random event denotes the relative frequency of occurrence of an experiment's outcome, when repeating the experiment. Frequentists consider probability to be the relative frequency
"in the long run" of outcomes.
Bayesians, however, assign probabilities to any statement whatsoever, even when no random process is involved. Probability, for a Bayesian, is a way to represent an individual's degree of belief in a statement, given the evidence.
这2个人成2派,也许对比看会给你一些启发。
当然每个人有每个人的思考结果,不说绝对的如何,只求知识的大成。
尽管老师会给解释这个概念,当年懂了,当学了统计,学到需要自己独立去处理统计方法,创造统计方法的时候就不懂了
他们不是两个人,frequentists是统计频率学派,bayesian是贝叶斯学派.这些概念我知道,因为我手头放着<统计手册>这本书,
