Model the Power-time (Pt) relationship for a set of data. This is done via
nonlinear least squares regression of four models: an inverse model; an
exponential model; a bivariate power function model; and a three parameter
inverse model. An S3 object of class "Ptmodels" is returned, which currently
has methods for print, coef, summary,
and predict. If inputs do not conform well to the models, a
warning message is generated. This function will make use of
minpack.lm::nlsLM
if available.
