论文摘要
我们得出了分析公式,该公式将Andreasen-Buge Style SABR模型的$α$,$ν$和$ρ$参数连接到ATM价格和期权价格,在接近ATM附近的四次罢工。基于这些公式,我们根据交换速率正向概率密度函数的导数给出了SABR参数的表征。我们在应用于利率期货期权市场的应用中测试了分析结果。
We derive analytic formulae which link $α$, $ν$ and $ρ$ parameters in Andreasen-Huge style SABR model to the ATM price and option prices at four strikes close to ATM. Based on these formulae we give a characterisation for the SABR parameters in terms of derivatives of the swap rate forward probability density function. We test the analytic result in the application to the interest rate futures option market.
