WebApr 7, 2024 · Its unique characteristics pose significant challenges to the analysis of such data and the existing methods often suffer grave consequences when the underlying model is misspecified. To address these difficulties, we propose a model-free two-stage generative approach for estimating the conditional survival function given predictors. WebJul 15, 2024 · Conditional characteristic function and moment are achieved in Section 3. Section 4 shows the explicit solution to bond price when the underlying asset satisfies the skew CIR process. In the appendix, for readers’ convenience, some basic analysis of symmetric local time is discussed. 2. Transformation.
