Hi blakeoft,

Yup. You're right. I just wanna find the gradient of the best fit line. It might not necessary get exactly the same value as what I manual generated from microsoft excel.
As long as it able to generate the gradient of best fit line and R-square value are fine enough.

I have around 10k item wanna to calculate the gradient of best fit line and R-square value of each item.
I unable to manual do it one by one.
Thus hope that got other alternative way able to count it automatic.

Really thanks and appreciate your advice.
