-;; Could you add logistic curve fitting to the current list?
-;;
-;; (I guess the key binding for a logistic curve would have to be `s'
-;; since a logistic curve is an `s' curve; both `l' and `L' are already
-;; taken for logarithms.)
-;;
-;; Here is the current list for curve fitting;
-;;
-;; `1'
-;; Linear or multilinear. a + b x + c y + d z.
-;;
-;; `2-9'
-;; Polynomials. a + b x + c x^2 + d x^3.
-;;
-;; `e'
-;; Exponential. a exp(b x) exp(c y).
-;;
-;; `E'
-;; Base-10 exponential. a 10^(b x) 10^(c y).
-;;
-;; `x'
-;; Exponential (alternate notation). exp(a + b x + c y).
-;;
-;; `X'
-;; Base-10 exponential (alternate). 10^(a + b x + c y).
-;;
-;; `l'
-;; Logarithmic. a + b ln(x) + c ln(y).
-;;
-;; `L'
-;; Base-10 logarithmic. a + b log10(x) + c log10(y).
-;;
-;; `^'
-;; General exponential. a b^x c^y.
-;;
-;; `p'
-;; Power law. a x^b y^c.
-;;
-;; `q'
-;; Quadratic. a + b (x-c)^2 + d (x-e)^2.
-;;
-;; `g'
-;; Gaussian. (a / b sqrt(2 pi)) exp(-0.5*((x-c)/b)^2).
-;;
-;;
-;; Logistic curves are used a great deal in ecology, and in predicting
-;; human actions, such as use of different kinds of energy in a country
-;; (wood, coal, oil, natural gas, etc.) or the number of scientific
-;; papers a person publishes, or the number of movies made.
-;;
-;; (The less information on which to base the curve, the higher the error
-;; rate. Theodore Modis ran some Monte Carlo simulations and produced
-;; what may be useful set of confidence levels for different amounts of
-;; initial information.)
