20 maj 2024 · As we mentioned previously, residual is the difference between the observed value and the predicted value at one point. We can calculate the residual as: e = y − ŷ. where: e – Residual; y – Observed value; and; ŷ – Predicted value. For instance, say we have a linear model of y = 2 × x + 2.
