Hi Walter, Thanks for the suggestion. I am not trying to fit my data in least sq method rather i am trying to draw an ellipse around and the data within the ellipse is within 90% confidential limit.

After fitting, you can plot a 90% ellipse around your data.

What does it mean you have a random matrix ? Do you know the parameters of the distribution the random value pairs stem from ?
