I tried to understand you question  but I am a bit lost (may be it is my English, and I do not understand you abbreviations).
Could you provide your data (by a link?) and clearly say what you do or expect or want? It is not clear what "least squares algorithm over the data set" should be, or "negative slopes".
Do you want some approximating 'curve' to your data? Or just a 'line'? Or what?
