The input arguments contain either return data or else mean and standard deviation data. Accordingly, number of input arguments is either 4 or 5. In case there 4 input arguments, the mean and standard deviation of data is computed from return data. See examples for details. returns Vector of daily P/L data data mu Mean of daily P/L data data sigma Standard deviation of daily P/L data data df Number of degrees of freedom in the t distribution cl VaR confidence level and must be a vector hp VaR holding period and must be a scalar |
