NLSstRtAsymptote: Horizontal Asymptote on the Right Side

Description

Provide an initial guess at the horizontal asymptote on the right side (i.e., large values of x) of the graph of y versus x from the xy object. Primarily used within initial functions for self-starting nonlinear regression models.

Usage

NLSstRtAsymptote(xy)

Arguments

xy
a sortedXyData object

Value

A single numeric value estimating the horizontal asymptote for large x.
