cdo = CDO(w, defProbs, recovery, attachements, detachements) w, 一般计算简单的CDO Gaussian copula model 都用125个 credit产品,具体原因我也没记住。w就是比重。w/np.sum(w) 也是比重%,没有大差别。 n = 125 w = 1./n*np.ones(n) # w/np.sum(w) 关于defProbs,我不是很清楚依据什么算出来...
qi (t | M) = probability( Z_i ≤ { [xi bar(t) - ai * M] / [根号(1-a^2)] } | M) 上面公式我们得出了图中的公式,右手边都是Constant,这里的概率是 φ,累计概率CDF。 现在让 P上标n (l, t),l 表示在时间t之前, 总共有l个投资组合违约的风险中性概率。
Theory of Gaussian Copula Model Latent Variable Concept Recap of Latent Variable Concept Suppose we have several ordinal variables which we measure on a group of experimental units. We wish to explore the correlations between them. We cannot assign numerical values to the levels of the ...
strain data at multiple monitoring points. Next, the failure probability of the bridge girder system was analyzed by combining the first-order second-moment method and bivariate Gaussian copula model with the proposed optimal regular vine model. Their work is currently ...
Summary This chapter introduces the Gaussian Copula model, in its different formulations concerning homogeneity and finiteness, illustrating the notions of implied correlation from collateralized debt obligation (CDO) tranche quotes. The Gaussian Copula model is a possible way to model the dependence of ...
Gaussian mixture copula model Wind speed forecasting is a complex task due to the strong random uncertainty, non-stationarity and high degree of volatility and deviations in the time-series data. However, the conventional single model based approach is normally built over a wide range of wind spee...
