Where can one find information on the covariance matrix?
One can find information on the covariance matrix on the Wikipedia website where there is much information about the mathematics involved. One can also find information on Mathworks.
How do you find covariance of two variables?
The covariance between two variables is simply the average product of the values of two variables that have been expressed as deviations from their respective means. ------------------------------------------------------------------------------------------------- A worked example may be referenced at: http://math.info/Statistics/Covariance

How can I calculate the portfolio standard deviation in Excel?
To calculate the portfolio standard deviation in Excel, you can use the formula SQRT(SUMPRODUCT(COVARIANCE MATRIX, WEIGHTS MATRIX, TRANSPOSE(WEIGHTS MATRIX))). This formula multiplies the covariance matrix of the assets, the weights of each asset in the portfolio, and the transpose of the weights matrix, then takes the square root of the sum of these products.

What is the importance of percentage composition?
Percent composition can be used to calculate the percentage of an element/compound in a mixture. From the percent composition, you can also find the empirical formula. And from the empirical formula you can find the actual molecular weight.
What is the formula to find the Percentage of decrease?
percentage of decrease = amount of decrease divided b the original amount and then multiply.
How can I calculate portfolio standard deviation in Excel?
To calculate portfolio standard deviation in Excel, you can use the formula SQRT(SUMPRODUCT(COVARIANCEMATRIX, TRANSPOSE(WEIGHTS), WEIGHTS)), where COVARIANCEMATRIX is the range of covariance values, and WEIGHTS is the range of weights assigned to each asset in the portfolio. This formula takes into account the covariance between assets and their respective weights to determine the overall risk of the portfolio.
Distinguish between analysis of variance and analysis of covariance?
) Distinguish clearly between analysis of variance and analysis of covariance.
What is the formula of percentage?
The formula of percentage is pi. This is used in math.
What formula do you use to get a percentage of 2 numbers?
If you have two numbers and want to find what percentage they are of each other, you can do some division. So for example, if you want to find out what percentage of 96 is 75, then you would divide 75 by 96 and format the result as a percentage. So if 75 is in cell A1 and 96 is in cell A2, then in another cell you would put the following formula: =A1/A2 It will be 78%. If you want to find what percentage of 75 is 96, then the formula would be: =A2/A1 It will be 128%. The numerical difference between 75 and 96 is 19. If you want to find what percentage of 75 or 96 19 is, then you divide the 19 by the 75 or by the 96. You could have a formula in a cell A3 which finds the difference between the two numbers first as follows: =A2-A1 That will be 19. Then to find what percentage of 75 19 is in another blank cell you would have the formula: =A3/A1 To find what percentage of 96 19 is in another blank cell you would have the formula: =A3/A2
