That you find in the regression equation. Notice how the coefficients column (labeled "Coef") are again the coefficients Table of Coefficients Predictor Coef SE Coef T P You really should look further down the page to see if the equation is a good You can use it for estimation purposes, but Predictor Variables: age, body, snatch Regression Equation The regression equation isĬlean = 32.9 + 1.03 age + 0.106 body + 0.828 snatch Minitab was used to perform the regression analysis.
Regression Analysis Explained Round 1: All Predictor Variables Included To involve k predictor variables instead of just one. + b kx k.īasically, everything we did with simple linear regression will just be extended This gives us a regression equation used for prediction of y = b 0 + b 1x 1 + b 2x 2 +. Parameters are estimated by b 0, b 1, b 2. ε is the error term or the residual that can't be explained by the model. Those parameters are the same as before, β 0 is the y-intercept or constant, β 1 is the coefficient on the first predictor variable, β 2 is the coefficient on the second predictor variable, and so on. , x k represent the k predictor variables.
If there are k predictor variables, then the regression equation model is Jerk lift Total The total weight (kg) lifted by the competitor Age Body The weight (kg) of the competitor Snatch The maximum weight (kg) lifted during the three attempts at a snatch lift Clean The maximum weight (kg) lifted during the three attempts at a clean and Data Dictionary Age The age the competitor will be on their birthday in 2004. The heaviest weights (in kg) that men who weigh more than 105 kg were able Going to use total because it's just the sum of snatch and clean. Will have several predictor (x) variables, age, body, and snatch. We will still have one response (y) variable, clean, but we Now we're going to look at the rest of the data that we collected about the
