y~. 和 y~x:z 是一个简单的formula。~和 : 是formula中的运算符,但它们与通常理解的数学运算符存在一定的差距。 公式formula中“~”符号将模型的响应变量(在~左侧)和解释变量(在~右侧)联系起来。常见于线性/一般线性模型(如lm(),glm()),树方法(如rpart())和图形表示(如coplot())以及其它一些场合(如t...
1. A=X+Y+Z 爱因斯坦 这个公式最早出自《纽约时报杂志》1929年8月18日塞缪尔·J·伍尔夫对爱因斯坦专访文章中。 “If A is success in life,” he replied, “I should say the formula is A=X+Y+Z, X being work and Y being play.”“And what,” I ask, “is Z?” “That,” he answered,...

\[ \int_{x^2 + y^2 \leq R^2} f(x,y)\,dx\,dy = \int_{\theta=0}^{2\pi} \int_{r=0}^R f(r\cos\theta,r\sin\theta) r\,dr\,d\theta.\] 效果如下: 1 \[ \int_0^1 \! \int_0^1 x^2 y^2\,dx\,dy.\] 效果如下: 1 2 3 4 5 6 7 8 9 10 11 12 13 14...
These multiples are also called factors. With the help of the factors of any expression, we can find the zeros of that expression. Answer and Explanation: Now in order to factor the expressions: x5−y5 and x7−y7, we have to first apply the factor formula that is given......
