A. examining individual observations to see whether the actual value of a dependent variable differs from the predicted value.
B. calculating the squared sum of residuals to draw inferences for the consistency of estimates.
C. transforming models with variables in level to logarithmic functions so as to understand the effect of percentage changes in the independent variable on the dependent variable.
D. sampling and collection of data in such a way to minimize the squared sum of residuals.
