Which of the following is true? A. a high R2 indicates that there is no omitted variable bias. B. a high R2 indicates that an added variable is statistically significant. C. a high R2 indicates that the independent variables are a true cause of the dependent variable. D. a high R2 indicates that the model has a high goodness-of-fit.Consider the regression model Wage = Bo + B, Age + 2 Experience + 3 Education. Suppose being estimated using the same random sample, which of the following can be compared with this model, using R2, in terms of their goodness-of-fit? O A. Wage = Bo + B, Age + 32 Experience. O B. Wage = Bo + B,Age + B2Age? + By Education. O C. log (Wage) = Bo + B, Age + B2 Experience. D. log (Wage) = Bo + B,Age + 2 Experience + B2 Education
