### Switching QQ Plot Axes, Generate New Series

Posted:

**Sun Oct 15, 2017 3:13 am**As far as I know, one of the easiest ways to make a Theoretical Quantile vs Standardized Residual plot is through the following commands:

That gave me something that looks like this:

Note that the x axis reads "Quantiles of Standardized Residuals". Unfortunately, I have to conform to the convention of having the random quantity on the Y axis (and fixed quantity on the x axis), so I will need to switch the axes somehow. Is there an argument for that? I did not come across one in the manual.

I would also accept a solution where one saves the theoretical quantile as a separate series. If I had that, I presume I could do:

Then I could overlay the standardized residuals as dots.

Code: Select all

`my_equation.makeresid(s) standardized_residuals`

standardized_residuals.qqplot theory
