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...
传统的 OLS(Ordinary Linear Regression) 是一个 convex optimization problem,很好求解。但有的时候我们希望自己换一些 loss function 来用,比如说使用 Mean Absolute Percentage Error?这里顺便介绍一下常用的模型评价指标吧。在 sklearn Machine Learning for beginners 中其实也讲到了。 这个时候,可能形式就不是很方便...
This formula is linear in the parameters. However, despite the name linear regression, it can model curvature. While the formula must be linear in the parameters, you can raise an independent variable by an exponent tomodel curvature. For example, if you square an independent variable, linear ...
