multi_line("The above figure represents the regression line being fitted to the training instances. If the regression line passes through all the points then the polynomial degree chosen overfits the data. Similarly, if the line does not touch even a single point, you might be underfitting the training instances.")
multi_line("The above scatter plot represents the spread of predicted and actual scores. Assuming out model perfectly fits the data we can expect the points spread across the y = x line.")
multi_line("The mean squared error is calculated as the sum of differences in actual and predicted result squared. The lower the MSE the better the model performs.")
multi_line("The Q-Q plot, or quantile-quantile plot, is a graphical tool to help us assess if a set of data plausibly came from some theoretical distribution such as a Normal or exponential. For example, if we run a statistical analysis that assumes our dependent variable is Normally distributed, we can use a Normal Q-Q plot to check that assumption. It's just a visual check, not an air-tight proof, so it is somewhat subjective. But it allows us to see at-a-glance if our assumption is plausible, and if not, how the assumption is violated and what data points contribute to the violation.")
