Logarithmic Regression Calculator. This calculator produces a logarithmic regression equation based on values for a predictor variable and a response variable. Simply enter a list of values for a predictor variable and a response variable in the boxes below, then click the “Calculate” button: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.
