Explanation:
Detailed explanation-1: -Residual (e) is the difference between the observed value of the dependent variable (y) and the predicted value (ลท) and each data point has one residual. Together the sum and the mean of the residuals are equal to zero ( e = 0 and e = 0).
Detailed explanation-2: -True The residual is the difference between the observed value of the dependent variable and the predicted value of the dependent variable.
Detailed explanation-3: -The observed value is a rate of a particular healthcare treatment, the predicted is the expected rate given the value of the independent variables.
