To compute the square number of the deviations from the average daily returns for 365 days, we multiply the variance by the number of days (365). The annualized standard deviation is found by taking the square root of the result: Variance = σ²daily = [Σ (r (t)) ² / (n - 1...
R2, also known as R squared, is a statistical measure that represents the proportion of the variance in the dependent variable that is explained by the independent variable(s) in a regression model. It is a value between 0 and 1, with higher values indicating a better fit of the model to...

Markowitz showed that assets can be combined to produce an 'Efficient' portfolio that will give the highest level of portfolio return for any level of portfolio risk, as measured by the variance or standard deviation. These portfolios can then be connected to generate what is termed an '...

in storage, it can lead to incorrect decryption and diagnosis. Some schemes [7,8] have introduced watermarking-based authentications, but these approaches add computational overhead to the process. The challenge remains in performing these tasks efficiently. This can be addressed by incorporating ...
