Xi is the value of the ith feature.; He would look at person and predict if s/he has lack of haemoglobin (red blood cells) or not. In the case of advertising data with the linear regression, we have rse value equal to 3.242 which means, actual sales deviate from the true regression line by approximately 3,260 units, on average.
