Learn linear regression, a statistical model that analyzes the relationship between variables. Follow our step-by-step guide to learn the lm() function in R.
#with regression line ggplot(df, mapping = aes(x=x, y=y)) + geom_point(color="blue") + geom_smooth(method='lm', se=FALSE, color="red") 我想要插入像这样的密度曲线(只是朝相反方向):
In this post I will show how to build a linear regression model. As an example, for this post, I will evaluate the association between vitamin D and calcium in the blood, given that the variable of interest (i.e., calcium levels) is continuous and the linear regression analysis must be...

ridge regression 设定训练集和测试集 这里有两种方法,先说简单的,1)n-fold cross validation,glmnet自带的功能,即每次把整个数据集拆成n份,n-1份做训练集,1份做测试集,然后做n次模型训练,n一般设定为10,如果样本量比较少的,可以酌情改成n=5。 cv.fit <- cv.glmnet(x,y,alpha = 1,family = 'gaussian...

Built the linear regression model using “GLM” package. It’s very similar to the “GLM” package in R.Let’s start with 1 variable.To train a linear regression model, use the lm() function that accepts a formula object as the first argument. Use the @formula to create the required ...
