The sample regression equation is denoted as follows, = To come up with the slope and y-intercept for the sample regression equation, we can use the method of least-squares. The method of least squares chooses the prediction line = o + 1x that minimizes the sum of the squared errors of prediction (y - )2 for all sample points. Hypothesis test ...

Linear Correlation and Regression. In this lecture, we’ll be looking at scatter plots and inferences you can make about them. There are two topics here: correlation, which deals with describing the relationship between two variables and deciding about its strength, and regression, which involves using values of one variable to make predictions about the values of the other variable.
