Скачать или смотреть Simple Linear Regression - Line of Best Fit, Errors and R Squared (CFA Level 1)

This clip introduces simple linear regression as fitting a straight line that best explains a dependent variable using one independent variable. It explains residuals as the vertical distances between actual points and the fitted line and describes minimizing the sum of squared errors as a way to choose the line that best fits the data. The segment also introduces R squared as the proportion of variance explained by the model and notes that a slope close to zero and low R squared indicate little meaningful linear relationship even though a line can always be estimated.
