WebTo use the formulae above we need to first calculate: Σx Σy Σx 2 Σy 2 Σxy This can be done by adding extra columns to our table: Summing each row we obtain the following data: Regression line y on x Let's start with b. Now we have b, let's find a where, So, a = -10.2 The line of regression y on x is y = a + bx So y = 0.986x - 10.2 Web12 mei 2024 · The slopes from a linear regression analysis using lm () are the coefficients. So, in this case, 30.318 is your Y-intercept. This gives you a regression equation of: Y = 30.318 + 0.245* (CRIM) + 5.8368* (CHAS) + 8.4846* (RM) The numbers 0.245, 5.8368, and 8.4846 are the coefficients for each variable and they are also the individual slopes.
