요약 | In this dissertation, we consider the problem of estimating a high dimensional covariance matrix in the presence of small sample size. The proposed Bayesian solution is general and can be applied to different functions of the covariance matrix i |
요약 | Using Monte Carlo simulations and real data analysis, we show that for small sample size, allocation estimates based on the sample covariance matrix can perform poorly in terms of the traditional measures used to evaluate an allocation for portf |
