Linear regression calculates an equation that minimizes the distance between the fitted line and all of the data points. Technically, ordinary least squares (OLS) regression minimizes the sum of the squared residuals. In general, a model fits the data well if the differences between the observed ...

Regression Metrics R Squared 📘 Wikipedia: Coefficient of determination R-squared, also known as coefficient of determination represents the proportion of variance (of y) that has been explained by the independent variables in the model. If R-squared = 80, this means that 80% of the ...
The red line is the fit of a machine learning model, in this case, a linear regression. The orange line represents the difference between the observed value and the prediction for that observation. As you can see, the residuals are calculated for each observation in the sample, be it the ...
Unlike the RMSE, the changes in MAE are linear and therefore intuitive. That is, MSE and RMSE punish larger errors more than smaller errors, inflating or magnifying the mean error score. This is due to the square of the error value. The MAE does not give more or less weight to different...

For linear regression, this is a horizontal line. Recall Recall measures how well an algorithm correctly predicts all of the true positives (TP) in a dataset. A true positive is a positive prediction that is also an actual positive value in the data. Recall is defined as follows: Recall =...
