lomolino: The lomolino SAR regression model

In mmSAR: mmSAR is an R package for the modelling of the Species-Area Relationship (SAR).

Description

S == c / 1 + z^log(f/A)

Usage

data(lomolino)

Format

The format is: List of 8 $ name : "Lomolino" $ formula : expression(S == over(c, 1 + z^log(over(f, A)))) $ paramnumber: 3 $ paramnames : "c" "z" "f" $ parLim : "Rplus" "Rplus" "Rplus" $ fun : model function $ rssfun : Residual Sum of Squares function $ init : initial values calculation $ form : a formula object for further calculations

Details

The lomolino model is sigmoid asymptotic. Parameter c is the upper asymptote. For further details and documentation please see the online documentation at http://mmsar.r-forge.r-project.org/
