table (often this is skipped). Interpreting the regression coefficients table. Confidence interval for the slope parameter. Testing hypothesis of zero slope parameter. Testing hypothesis of slope parameter equal to a particular value other than zero. uncertainty in slope of best fit line Testing overall significance of the regressors. Predicting y given values of regressors. Fitted how to find standard deviation of slope and intercept values and residuals from regression line. Other regression output. This handout is the place to go to for statistical inference for formula for finding error in slope two-variable regression output. REGRESSION USING THE DATA ANALYSIS ADD-IN This requires the Data Analysis Add-in: see Excel 2007: Access and Activating the Data Analysis Add-in The data used are in carsdata.xls The https://www.youtube.com/watch?v=eV-RKGGrtA8 method is explained in Excel 2007: Two-Variable Regression using Data Analysis Add-in Regression of CARS on HH SIZE led to the following Excel output: The regression output has three components: Regression statistics table ANOVA table Regression coefficients table. INTERPRET REGRESSION STATISTICS TABLE Explanation Multiple R 0.894427 R = square root of R2 R Square 0.8 R2 = coefficient of determination Adjusted R Square 0.733333 Adjusted R2 http://cameron.econ.ucdavis.edu/excel/ex53bivariateregressionstatisticalinference.html used if more than one x variable Standard Error 0.365148 This is the sample estimate of the standard deviation of the error u Observations 5 Number of observations used in the regression (n) The Regression Statistics Table gives the overall goodness-of-fit measures: R2 = 0.8 Correlation between y and x is 0.8944 (when squared gives correlation squared = 0.8 = R2 ). Adjusted R2 is discussed later under multiple regression. The standard error here refers to the estimated standard deviation of the error term u. It is sometimes called the standard error of the regression. It equals sqrt(SSE/(n-k)). It is not to be confused with the standard error of y itself (from descriptive statistics) or with the standard errors of the regression coefficients given below. INTERPRET ANOVA TABLE df SS MS F Signifiance F Regression 1 1.6 1.6 12 0.04519 Residual 3 0.4 0.133333 Total 4 2.0 The ANOVA (analysis of variance) table splits the sum of squares into its components. Total sums of squares = Residual (or error) sum of squares + Regression (or explained) sum of squares. Thus Σ i (yi - ybar)2 = Σ i (yi - yhati)2 + Σ i (yhat

STEYX and FORECAST. Fitting a regression line using Excel function LINEST. Prediction using Excel function TREND. For most purposes these Excel functions are unnecessary. It is easier to instead use the http://cameron.econ.ucdavis.edu/excel/ex54regressionwithlinest.html Data Analysis Add-in for Regression. REGRESSION USING EXCEL FUNCTIONS INTERCEPT, SLOPE, RSQ, STEYX and FORECAST The data used are in carsdata.xls The population regression model is: y = β1 + β2 x + u We wish to estimate the regression line: y = b1 + b2 x The individual functions INTERCEPT, SLOPE, RSQ, STEYX and FORECAST can be used to get key results for in slope two-variable regression INTERCEPT(A1:A6,B1:B6) yields the OLS intercept estimate of 0.8 SLOPE(A1:A6,B1:B6) yields the OLS slope estimate of 0.4 RSQ(A1:A6,B1:B6) yields the R-squared of 0.8 STEYX(A1:A6,B1:B6) yields the standard error of the regression of 0.36515 0.8 FORECAST(6,A1:A6,B1:B6) yields the OLS forecast value of Yhat=3.2 for X=6 (forecast 3.2 cars for household of size 6). Thus the estimated model is y = 0.8 + 0.4*x with R-squared error in slope of 0.8 and estimated standard deviation of u of 0.36515 and we forecast that for x = 6 we have y = 0.8 + 0.4*6 = 3.2. REGRESSION USING EXCEL FUNCTION LINEST The individual function LINEST can be used to get regression output similar to that several forecasts from a two-variable regression. This is tricky to use. The formula leads to output in an array (with five rows and two columns (as here there are two regressors), so we need to use an array formula. We consider an example where output is placed in the array D2:E6. First in cell D2 enter the function LINEST(A2:A6,B2:B6,1,1). Then Highlight the desired array D2:E6 Hit the F2 key (Then edit appears at the bottom left of the dpreadsheet). Finally Hit CTRL-SHIFT-ENTER. This yields where the results in A2:E6 represent Slope coeff Intercept coeff St.error of slope St.error of intercept R-squared St.error of regression F-test overall Degrees of freedom (n-k) Regression SS Residual SS In particular, the fitted regression is CARS = 0.4 + 0.8 HH SIZE with R2 = 0.8 The estimated coefficients have standard errors of, respectively, 0.11547 and 0.382971.
