The actual value of a dependent variable will generally differ from the regression equation estimate due to A)unaccounted for random variation. B)the inability of the nonlinear Solver to find optimal values. C)not building the regression model with enough data. D)the model R²not equal to 1.

The actual value of a dependent variable will generally differ from the regression equation estimate due to unaccounted for random variation. No matter how well a regression model is built or how much data is used, there will always be some degree of random variation in the data that cannot be explained by the model. This is why the actual value of the dependent variable will often differ from the estimated value predicted by the regression equation. Choices B and C are incorrect because they do not accurately reflect the reason for the difference between the actual and estimated values, and choice D is not a valid option.
