- 关于第4点,第六章p19图25左边坐标轴就更合理。
- 概率密度函数里,随机变量的数字应该写在下标上,比如图25右边和式35等一些地方的PDF的X1,X2。
- 关于字体的问题,book5里使用的字体,大写的X和小写的x容易搞混。

以及ch6 p26 图35,左图,阴影部分应该是f_{X2}(x2)吧?

几处笔误和记号问题:
- ch8 p10 公式13,第二个式子,条件方差的表达式有误,等式左边应该是var(Y|X)。
- ch8 p12 公式19,等号右边第一项,应该为 E(cov(X_1|Y, X_2|Y))。
- 在条件概率中经常有X=x,Y=y这样的写法,表示随机变量的取值,但是小写的x,y又经常作为概率密度函数的自变量,容易混淆。可以将随机变量和概率密度函数的固定取值记为x_0, y_0。
- ch9 p3公式1以及后面的地方,高斯函数指数项里的负号应该放在分数线外面
