**Portfolio standard deviation from variance-covariance**

Using Stata for One-Way Analysis of Variance We have previously shown how the following one-way ANOVA problem can be solved using SPSS. We will now approach it using Stata.... 5/10/2012Â Â· Learn how to conduct an analysis of covariance (ANCOVA) in Stata. In the video the blue dots and lines correspond to union=1 and red dots and lines correspond to union=0 regardless of what Chuck

**Using Stata for One-Way Analysis of Variance**

Thus, we need standard deviation of the two assets, proportion of investment in each asset (weights), and the covariance term between the two assets. In Excel, we can find the standard deviation by â€¦... 5/10/2012Â Â· Learn how to conduct an analysis of covariance (ANCOVA) in Stata.

Then find variance -covariance matrix in Stata or Mata (We can make a Mata function for that) 7. Find standard deviation by assigning equal weights to each stock. 8. Get the SD from Mata and write it to the relevant portfolio. 9. Delete the extra data points created in step 3 . Our Stata Code . We have developed easy to use yet robust codes for the above steps. The codes need just a basic...

## How To Find Covariance In Stata

### If the question is about the covariance between how the dummies are represented, then it depends. For example, if you have a categorical variable with three levels ( L1 L2 L3 ), represented with 2 dummy variables L2 and L3 , then there is no way the covariance between the constructed L2 and L3 variables is zero, as they certainly are not independent.
