hypothesis testing with efficient method of moments estimation

... advantage of being valid for a whole class of models with other moment-based estimation techniques, and at the same time it achieves the first-order asymptotic efficiency of likelihood- based methods. ... biases of the model option prices, while the MARE statistic measures the dispersion of relative biases of the model prices. The difference between MARE and MRE suggests the direction of the bias of ... Estimation of other submodels is fairly straightforward. Submodel 2 takes the SV part of the stock returns. Submodel 3 takes the SV part of the interest rates. Table 6.3 reports the results of...
