    摘要: 利用獨立成份分析的功能，解決求解投組分配的困難，再用LAVE,GARCH,跟RiskMetrics 三種不同的變異數方法去配適獨立成份的動態過程，並利用台股指數進行一天的風險值預期，共一千天，最後用回顧測試檢定模型的優劣
    The Value at Risk (VaR) measures the potential loss in value of risky asset or portfolio over a defined period for a given confidence interval. The traditional way needs to estimate corresponding distribution and process of portfolio, which is very difficult. Independent component analysis (ICA) is designed for detection of blind folded signals and retrieves out of a high-dimensional time series stochastically independent source components. We can use the property of independence to estimate distribution of portfolio easily. This paper uses three different volatility estimate methods in conjunction with independent component process to calculate value at risk.
