Simple Regression: What should you know for test time? On a test, you should be able to perform manual calculations. But the sample size will be very small. You must use the formulas to compute: regression equation, SSR, SSE, SST, r^2, r, standard error, confidence interval for mean of Y, prediction interval for individual value of Y and similar computations. You should also be familiar with Excel and its output. Given an Excel printout, you must be able to interpret it and use it to answer various questions such as: How many observations were in the data What is the slope (b1) What is the intercept (bo) What is the correlation coefficient (r) What is the coefficient of determination (r^2) What is the standard error What are: SSE, SSR, SST What % of variation in Y is explained by X etc. ... Multiple Regression: Q/A about Interval Estimation and Test Questions Q: Does Excel compute Confidence and Prediction Intervals which are discussed in the simple and multiple regression chapters?
