2. Realized variance - Wikipedia

   en.wikipedia.org/wiki/Realized_variance

   The realized volatility is the square root of the realized variance, or the square root of the RV multiplied by a suitable constant to bring the measure of volatility to an annualized scale. For instance, if the RV is computed as the sum of squared daily returns for some month, then an annualized realized volatility is given by 252 × R V ...

3. Form 1099 - Wikipedia

   en.wikipedia.org/wiki/Form_1099

   For a variety of reasons some Form 1099 reports may include amounts that are not actually taxable to the payee. A typical example is Form 1099-S for reporting proceeds (not gain) from real estate transactions. The Form 1099-S preparer will report the sales proceeds without regard to the amount of the taxpayer's "basis" in the real estate sold.

4. Variance - Wikipedia

   en.wikipedia.org/wiki/Variance

   An advantage of variance as a measure of dispersion is that it is more amenable to algebraic manipulation than other measures of dispersion such as the expected absolute deviation; for example, the variance of a sum of uncorrelated random variables is equal to the sum of their variances. A disadvantage of the variance for practical applications ...

5. Mean absolute difference - Wikipedia

   en.wikipedia.org/wiki/Mean_absolute_difference

   The mean absolute difference (univariate) is a measure of statistical dispersion equal to the average absolute difference of two independent values drawn from a probability distribution. A related statistic is the relative mean absolute difference , which is the mean absolute difference divided by the arithmetic mean , and equal to twice the ...

6. Average absolute deviation - Wikipedia

   en.wikipedia.org/wiki/Average_absolute_deviation

   In the general form, the central point can be a mean, median, mode, or the result of any other measure of central tendency or any reference value related to the given data set. AAD includes the mean absolute deviation and the median absolute deviation (both abbreviated as MAD ).

7. Coefficient of variation - Wikipedia

   en.wikipedia.org/wiki/Coefficient_of_variation

   The coefficient of variation fulfills the requirements for a measure of economic inequality. [ 20 ] [ 21 ] [ 22 ] If x (with entries x i ) is a list of the values of an economic indicator (e.g. wealth), with x i being the wealth of agent i , then the following requirements are met:
