什么是概率密度函數(shù)的歸一性？

人認(rèn)為最簡單的理解就是： 概率密度函數(shù)的圖形在X軸上方，這是非負(fù)性，同時(shí)，它與X軸所包圍的整個(gè)曲邊面積為1，即歸一性。

概率指事件隨機(jī)發(fā)生的機(jī)率，概率密度的概念也大致如此，指事件發(fā)生的概率分布。 在數(shù)學(xué)中，連續(xù)型隨機(jī)變量的概率密度函數(shù)（在不至于混淆時(shí)可以簡稱為密度函數(shù)）是一個(gè)描述這個(gè)隨機(jī)變量的輸出值，在某個(gè)確定的取值點(diǎn)附近的可能性的函數(shù)。probability density function，簡稱PDF。 概率密度函數(shù)加起來就是概率函數(shù)（離散變量）,或者積分（連續(xù)變量）。
