How can I calculate portfolio variance in Excel?
To calculate portfolio variance in Excel, you can use the formula SUMPRODUCT(COVARIANCE.S(array1,array2),array1,array2), where array1 and array2 are the returns of the individual assets in your portfolio. This formula takes into account the covariance between the assets and their individual variances to calculate the overall portfolio variance.
What is the difference between negative price variance and volume variance?
Negative price variance is when the cost is less than budgeted. Volume variance is a variance in the volume produce.
What is a variance report?
It is a report to see how a business is doing by comparing one set of figures to another. The variance is the number in between and can be useful in forecasting or to chart performance.
What is a positive or negative variance of a budget?
A variance is the difference between the projected budget and the actual performance for a particular account. A negative variance means that the budgeted amount was greater than the actual amount spent. A positive variance means that the budgeted amount was less than the actual amount spent. Note there is some debate over whether a negative variance means an underrun or an overrun. The Project Management Institute, however, endorses the accepted convention that a negative variance is a bad thing, and a positive variance a good thing.
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.
What is difference between covariance and variance?
Covariance: An Overview. Variance refers to the spread of a data set around its mean value, while a covariance refers to the measure of the directional relationship between two random variables.
What is a variance covariance matrix?
Briefly, the variance for a variable is a measure of the dispersion or spread of scores. Covariance indicates how two variables vary together. The variance-covariance matrix is a compact way to present data for your variables. The variance is presented on the diagonal (where the column and row intersect for the same variable), while the covariances reside above or below the diagonal.
What is the difference between analysis of variance and analysis of covariance?
ANOVA characterises between group variations, exclusively to treatment. In contrast, ANCOVA divides between group variations to treatment and covariate. ANOVA exhibits within group variations, particularly to individual differences.

What is the difference between anova and aov?

What is difference between the amount budgeted and the actual amount is called?
Difference between actual amount and budgeted amount is called "Variance" and variance analysis is done to find out the reasons for variance
How can I calculate portfolio variance in Excel?
To calculate portfolio variance in Excel, you can use the formula SUMPRODUCT(COVARIANCE.S(array1,array2),array1,array2), where array1 and array2 are the returns of the individual assets in your portfolio. This formula takes into account the covariance between the assets and their individual variances to calculate the overall portfolio variance.
Purpose of variance analysis?
Variance analysis shows the deviation of an organization's financial performance from the set standard in the budget. An organization will promptly address the deviations.

What is tau-squared statistics in random effects meta-analysis for?
It is the estimate of between-study variance, to quantify heterogeneity
What does the acronym ANOVA stand for?
The abbreviation ANOVA stands for analysis of variance. It is used for carrying out comparative analysis of the statistical methods to determine if there is any relationship between data points.
