NLSstAsymptotic
Fit the Asymptotic Regression Model

### Description

Fits the asymptotic regression model, in the form b0 + b1*(1-exp(-exp(lrc) * x)), to the xy data.

### Usage

    NLSstAsymptotic(xy)

### Arguments

xy | a sortedXyData object.

Value
returns a length-3 numeric value with the following components.

b0 | represents the estimated intercept on the y-axis.
b1 | represents the estimated difference between the asymptote and the y-intercept.
lrc | represents the estimated logarithm of the rate constant.
