I believe you are misusing the outlier analysis. It applies to linear correlations. You have a non-linear relationship between two variables. I would not expect it to correctly identify outliers and non-outliers in such a case.

Hi Mark

Appreciate for your input. You are correct. Both variables are non-linear. Which method can I use to detect outliers from non-linear variables.
