WebAug 8, 2010 · For fitting y = Ae Bx, take the logarithm of both side gives log y = log A + Bx. So fit (log y) against x. Note that fitting (log y) as if it is linear will emphasize small values of y, causing large deviation for large y. This is because polyfit (linear regression) works by minimizing ∑ i (ΔY) 2 = ∑ i (Y i − Ŷ i) 2.
