Standard Deviation and Variance -- how are they calculated, and why are they calculated that way?
Variance Calculator is an online tool to find the variance of the given numbers. It makes calculation easy and fun. If set of numbers are given, then it can easily find the variance of that numbers.
The Calculating VaR (Value at Risk) video course takes an in-depth look at the calculation methodologies of the Value at Risk measure. We review Value at Risk (VaR) calculation methods in particular the Variance-covariance approach and the Historical simulation approach. We build a simple portfolio comprising of Euro, Australian dollar, Yen, GBP, Brent, WTI, Gold and Natural Gas and calculate VaR for the portfolio using both of these methodologies.
Calculation of the standard deviation using data from Table 4
We start with a review of Value at Risk (VaR) calculation methods including VaR by variance-covariance, VaR by historical simulation and VaR by Monte Carlo simulation, build a simple portfolio and calculate VaR for the first of the above two methods. We close with a review of applying a Value at Risk (VaR) approach to risk management within the petrochemical industry as well as a review of known issues in Value at Risk (VaR) calculations and results.
