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...

The slope of the line represents the change in y for a unit change in x, while the y-intercept represents the value of y when x is equal to 0. There are two types of linear regression analysis: simple linear regression and multiple linear regression. Simple linear regression involves only...
Simple linear regression is used to model the relationship between two continuous variables. Often, the objective is to predict the value of an output variable based on the value of an input variable.
In simple linear regression, the topic of this section, the predictions of Y when plotted as a function of X form a straight line.The example data in Table 1 are plotted in Figure 1. You can see that there is a positive relationship between X and Y. If you were going to predict Y ...
