SSgaussAre: Self-Starting nls area of gaussian model

In krzysiektr/FitCurve: Nonlinear Curve Fitting

Self-Starting nls area of gaussian model

Description

Area version of gaussian function.

Usage

SSgaussAre(input,y0,A,xc,w)

Arguments

input	a numeric vector of values at which to evaluate the model.
y0	offset
A	area
xc	center
w	width

Value

a numeric vector of the same length as input. It is the value of the expression y0+(A/(w*sqrt(pi/2)))*exp(-2*(x-xc)^2/(w^2)).

Note

This is primarily intended for use in formulae given to the nls function or similar functions for example mle2.
