- Which of the following statements is true? 未知类型：{'options': ['When the standard error of an estimate increases, the confidence interval for the estimate narrows down.', 'Standard error of an estimate does not affect the confidence interval for the estimate.', '', ''], 'type': 102}
- Which of the following statistics and procedures can be used to determine whether a linear model should be employed?
- allows the effect of changing one of the binary independent variables to depend on the value of the other binary variable. A: occurs when a selection process influences the availability of data and that process is related to the dependent variable. B: is only important for finite sample results. C: results in the OLS estimator being biased, although it is still consistent. D: is more important for nonlinear least squares estimation than for OL
- In a linear stretching transformation ( s=ar+b ),when a and b take any value,can be gray value respectively from 24 and 156 to 15 and 213 ?
- If the coefficient of correlation r = 0, then there is no linear relationship whatsoever between the dependent variable y and the independent variable x.
