Logarithmic Regression

logfit(vx, vy, vg) Returns a vector containing the coefficients for a logarithmic curve of the form a·ln(x + b) + c that best approximates the data in vx and vy using guess values in vg.

lnfit(vx, vy) Returns a vector containing the coefficients for a logarithmic curve of the form a·ln(x) + b that best approximates the data in vx and vy.

The logfit and lnfit functions employ the Levenberg-Marquardt method for minimization.
