Get (x & y) intercept values from linear fit of the linear region of a curve/data and store them in a new column
I have JMP data table with data from several parts for which a Capacitance 'C' has been measured as a function of reverse voltage 'V' (0 to -5 V in -0.1V step). A plot of [1/C]^2 vs V has a linear part for small reverse bias (say from 0 V to -0.5V and data is available at 0, -0.1, -0.2, -03, -0.4 -0.5 V within this range). How to do a linear fit to the points between 0 to -5V for each part, extrac...
