So Y is the variable in question and X plays the role of input information relevant to Y. Sometimes, Y is described as the "response" to the "factor" X. In itself, X might or might not be a random variable, but from the point of view of the model, X is not random because the...
2. 书籍导读 - Section 3.1 - Simple Linear Regression 简单线性回归(Simple Linear Regression)也叫做一元线性回归,此处的 “简单”和“一元”都是指只有一个变量和因变量。公式:Y \approx \beta_0 + \beta_1X是统计学的写法,机器学习领域我们比较常见的写法是f(x) = wx+b。这俩公式说的是同一函数在不...
