The coefficient of determination, denoted as R-squared, is a measure of how well the regression line fits the data points. It ranges from 0 to 1, where 0 means that there is no relationship between the predictor and the response variables and 1 means that the regression line perfectly fits the data points. Negative values of R-squared are also possible, indicating that the regression line is a poor fit for the data. However, these negative values are confined to situations where the regression line is worse than predicting the mean of the response variable.
