Fitting equation
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. WebThe general form equation for this kind of curve is… y = k√x. A suitable conclusion statement from such a relationship would be that… y is proportional to the square root …
