Linear Regression on Boston Housing Dataset by Animesh Agarwal

WebbWe will start by using the lm() function to fit a simple linear regression model, with medv as the response and lstat as the predictor. The basic syntax is {}, where y is the response, x is the predictor, and data is the data set in which these two variables are kept. WebbIn machine learning, the variable that is being modeled is called the target variable; it's what you are trying to predict given the features. For this dataset, the suggested target is MEDV, the median house value in 1,000s of dollars. Run the next cell to see the shape of the target: Figure 1.27: Code for viewing the shape of the target dementia icd-10 without behavior
