- Subject: Plotting Bivariate Normal Eliptical Contours
- Lines: 16
-
- Has anyone written a SAS macro to generate and plot elipical
- contours for the bivariate normal density function based on the
- means, standard deviations, and correlation coefficient for a pair
- of variables? This is discussed in Donald Morrison's "Applied
- Linear Statistical Methods" (1983, pp. 24-25). I would eventually like
- to be able to overlay the elipse associated with various bivariate
- densities (i.e. 5%, 1%, .1%) on a scatter plot of the actual data.
- Any help or ideas would be greatly appreciated.
