Hi,

I would like to if there is anyway to increase the number of significant digits in curve fitting. I tried to fit and got a fittiong co-efficient as below.
inear model Poly1:
f(x) = p1*x + p2
where x is normalized by mean 0.0002051 and std 0.0002143
Coefficients (with 95% confidence bounds):
p1 = 8.119e-05 (8.043e-05, 8.195e-05)
p2 = -43.82 (-43.82, -43.82)

But for the confidence bound is the same as co efficient, is there anyway i can increase the significant digits in the parameters?
