The app allows users to explore weighted regression by either inputting their own data or generating random values. Users can adjust weights, visualize the regression output through a graph, and analyze the effect on the regression equation and $R^2$ value, with options to view or hide residuals.
The plot will be updated as you enter data in the table. You can also drag the points to see the effect on the regression line. In weighted linear regression mode, you can drag the error bars to change the weights of the data points and see how it affects the regression line.
