We derive its order of accuracy. Afterwards, we suggest its use in calibration and show that it can be reduced to a simple optimization problem. To test the calibration methodology, we use the simulated data from the Cox-Ingersoll- Ross model where the exact bond prices can be computed. We show that using the approximation in the calibration recovers the parameters with a high precision.}, issn = {}, doi = {https://doi.org/}, url = {http://global-sci.org/intro/article_detail/ijnamb/255.html} }
