The parameters for the relationship ln(
x
)=f(
t
) are estimated as follows:
A straight line is fitted to a subset of paired datapoints by means of linear regression. Additional data are included in the initial subset and computations of slope are performed repeatedly until its value is > 95 % of the maximum slope determined for the initial subset.
This method was adopted from the R-package by
Petzold (2017)
and originally published by
Hall
et al.
(2015)
