以及ch6 p26 图35,左图,阴影部分应该是f_{X2}(x2)吧? |
谢谢你!这些建议都太好了!非常感谢。鸢尾花书对纠错多的读者有赠书感谢,下一批是《编程不难》的赠书。方便的话,请发我你的邮寄信息,姓名地址电话。邮箱地址,在PDF左下角。《编程不难》明年初上架,一旦上架由出版社安排寄送。
祝好!

几处笔误和记号问题:
1. 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)。
2. ch8 p12 公式19,等号右边第一项,应该为 E(cov(X_1|Y, X_2|Y))。
3. 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。
4. 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
