On this basis, the authors construct yield to maturity curve and obtain regression equation of the curve through establishing a model.

在此基础上，构造了国债收益率曲线并通过建模获得了收益率曲线的回归方程。

The Yield to maturity would be higher for a discount bond, based on the fact that you are still earning interest on par even if you paid under par.
