Sensitivity analysis of the results may include the following with the exception of
A)stability over time analysis of the estimated multipliers.
B)using homoskedasticity only rather than HAC standard errors.
C)investigation of omitted variable bias.
D)looking at different computations of the HAC standard errors.

Question

Quizplus · Accepted Answer

All the other options are valid methods of sensitivity analysis, but using homoskedasticity only rather than HAC standard errors is not an appropriate way of conducting sensitivity analysis. HAC standard errors are used to account for autocorrelation or heteroskedasticity in the data, and omitting them may lead to biased estimates. Therefore, it is not a recommended approach for sensitivity analysis.
