R. Schwarz, to fit data to +;; nonlinear curves. Currently, the only the following curves are +;; supported: +;; The logistic S curve, y=a/(1+exp(b*(t-c))) +;; Here, y is usually interpreted as the population of some +;; quantity at time t. So we will think of the data as consisting +;; of quantities q0, q1, ..., qn and their respective times +;; t0, t1, ..., tn. + +;; The logistic bell curve, y=A*exp(B*(t-C))/(1+exp(B*(t-C)))^2 +;; Note that this is the derivative of the formula for the S curve. +;; We get A=-a*b, B=b and C=c. Here, y is interpreted as the rate +;; of growth of a population at time t. So we will think of the +;; data as consisting of rates p0, p1, ..., pn and their +;; respective times t0, t1, ..., tn. + +;; The Hubbert Linearization, y/x=A*(1-x/B) +;; Here, y is thought of as the rate of growth of a population +;; and x represents the actual population. This is essentially +;; the differential equation describing the actual population. + +;; The Levenberg-Marquardt method is an iterative process: it takes +;; an initial guess for the parameters and refines them. To get an +;; initial guess for the parameters, we'll use a method described by +;; Luis de Sousa in "Hubbert's Peak Mathematics". The idea is that +;; given quantities Q and the corresponding rates P, they should +;; satisfy P/Q= mQ+a. We can use the parameter a for an +;; approximation for the parameter a in the S curve, and +;; approximations for b and c are found using least squares on the +;; linearization log((a/y)-1) = log(bb) + cc*t of +;; y=a/(1+bb*exp(cc*t)), which is equivalent to the above s curve +;; formula, and then tranlating it to b and c.
