0000048807 00000 n As long as your model satisfies the OLS assumptions for linear regression, you can rest easy knowing that youre getting the best possible estimates.. Regression is a powerful analysis that can analyze multiple variables simultaneously to answer b The resulting distribution of IRFs can then be cut to obtain the error band of the point estimate. Essentially, a more efficient estimator, needs fewer input data or observations than a less efficient one to achieve the CramrRao bound.An efficient estimator is characterized by having the smallest possible variance, indicating that there is a small The same process is used in the Heston model to model stochastic volatility.
