Sigma(d) = Standard Deviation of Negative Asset Returns #6 - Modigliani Risk-Adjusted Performance Also known as Modigliani-Modigliani measure or M2, it is used for arriving at the risk-adjusted return of an investment portfolio. It is used for measuring the return from a portfolio adjusted for...
The sigma squared or sigma2 value is the variance of the model residuals. The sigma term describes the volatility of the hypothesized process. If you have highly volatile data but a very low sigma squared score, or conversely non-volatile data but a high sigma squared score, that is a sign...
We obtain the final prediction vector h by applying a so-called activation function to the vector z. In this case, the activation function is represented by the letter sigma. An activation function is only a nonlinear function that performs a nonlinear mapping from z to h. There...

Mathematically, Standard Deviation is calculated by taking the square root of the Variance. Variance measures the average squared difference between each Data Point and the Mean. While, Standard Deviation brings this measure back to the original units of the data, making it more interpretable. A ...
Square means to multiply by itself. For example, 2 squared=2 x 2=4, or 8 squared=8 x 8=64 What does a square number mean in math? Square numbers formed when two same numbers multiply together and the answer is the square number. For example: 6 x 6=36, 6 and 6 are the same ...
What is the relationship between standard error and maximum error? What symbol is used to identify the standard error of M? a. sigmaM b. mu c. sigma d. MM What is the effect of n on the standard error of the mean? What is the mode, and with what type of data is it most approp...
a. What is Correlation of {eq}(X,\ Y) {/eq}? b. What is {eq}Var (X - 2 Y) {/eq}? c. What is {eq}Var (X + Y) {/eq}? Variance and Covariance of Random Variables: The variance of a random va...
column. Add together all of the x values, all of the y values, all of the xy values, all of the x2values, and all of the y2values, and then put the results at the bottom of the corresponding column in your new row. You can label your new row "sum" or use a sigma (Σ) ...
1). Since the electroweak couplings of all three charged leptons are the same, the ratio of branching fractions for these two decays is naively expected to be unity, and it can indeed be calculated theoretically with high precision in a given range of the produced dilepton mass squared q2....
