Memorize and be able to use. Least Squares estimates: You will not have to memorize the LSEs for slope and y-intercept, but you should be able to use them if they are given to you, and you should be able to calculate them if the equations are given to you. Note: Understanding what the equations mean and why they are relevant is just as important as knowing the equation itself. This class is very conceptual, so I suggest understanding the concepts as opposed to trying to memorize formulas and algorithms....
