av L Söderberg · 2013 · Citerat av 2 — slope of the fitted regression line with equation has a value close to 1 and R. 2 value of 0.999. A fitted regression line has been estimated in Microsoft Excel.

In that case you can simply use Excel worksheet functions or formulas. SLOPE (), INTERCEPT () and RSQ () are the main worksheet function you will need to find linear regression coefficients. regression using excel functions intercept, slope, rsq, steyx and forecast The data used are in carsdata.xls The population regression model is: y = β 1 + β 2 x + u Estimated regression equation: We can use the coefficients from the output of the model to create the following estimated regression equation: exam score = 67.67 + 5.56*(hours) – 0.60*(prep exams) We can use this estimated regression equation to calculate the expected exam score for a student, based on the number of hours they study and the number of prep exams they take. For this particular example, our fitted polynomial regression equation is: y = -0.1265x 3 + 2.6482x 2 – 14.238x + 37.213 This equation can be used to find the expected value for the response variable based on a given value for the explanatory variable. As usual, we can use the formula described above for prediction.
