Web20 de mar. de 2024 · The first workaround that comes to mind would be to just take the absolute value, like this: y_i-f (x_i) ∣yi − f (xi)∣. Let’s call this the sum of absolute residuals (SOAR). An alternative would be to square each term instead, like this: (y_i-f (x_i))^2 (yi − f (xi))2. Let’s call this the sum of squared residuals (SOSR). SOAR vs SOSR Simple linear regression is a parametric test, meaning that it makes certain assumptions about the data. These assumptions are: 1. Homogeneity of variance (homoscedasticity): the size of the error in our prediction doesn’t change significantly across the values of the independent variable. 2.
