How can I count data points that lay outside of the main plot line?
I have a plot in which most data points create a sigmoid line, but some are spread throughout the plot area, these points dont fit the curve. I would like to count them to know the ratio between the main curve and the data points that dont fit, any ideas?

Thanks,

Raz
