Three-parameter Michaelis-Menten function

A three-parameter (shifted) Michaelis-Menten function where b is fixed at -1 and f at 1.

Usage

MM.3(fixed = c(NA, NA, NA), names = c("c", "d", "e"), ...)

Arguments

fixed

numeric vector of length 3, specifying fixed parameters (use NA for non-fixed parameters).

names

character vector of length 3, specifying the names of the parameters (default: c, d, e).

...

additional arguments to llogistic.

Value

See llogistic.

Details

The three-parameter Michaelis-Menten function is $$f(x) = c + \frac{d-c}{1+(e/x)}$$
