To optimize the investment portfolio, conditional value at risk is a new approach. To amend Copula-GARCH模型下的两资产期权定价 the non-normal distribution of return on assets, and the non-linear correlation between return, the … Expand

Revisiting Fama–French factors' predictability with Bayesian modelling and copula‐based portfolio optimization

This study is investigating the predictability of the five Fama–French factors and explores their optimal portfolio allocation for factor investing during 2000–2017. Firstly, we forecast each factor … Expand

Copula-GARCH模型下的两资产期权定价

Classes (S4) of commonly used elliptical, Archimedean, extreme-value and other copula families, as well as their rotations, mixtures and asymmetrizations. Nested Archimedean copulas, related tools and special functions. Methods for density, distribution, random number generation, bivariate dependence measures, Rosenblatt transform, Kendall distribution function, perspective and contour plots. Fitting of copula models with potentially partly fixed parameters, including standard errors. Serial independence tests, copula specification tests (independence, exchangeability, radial symmetry, extreme-value dependence, goodness-of-fit) and model selection based on cross-validation. Empirical copula, smoothed versions, and non-parametric estimators of the Pickands dependence function.
