%description
Linear and nonlinear regression analysis common in agricultural science
articles (Archontoulis & Miguez (2015). <doi:10.2134/agronj2012.0506>).
The package includes polynomial, exponential, gaussian, logistic,
logarithmic, segmented, non-parametric models, among others. The functions
return the model coefficients and their respective p values, coefficient
of determination, root mean square error, AIC, BIC, as well as graphs with
the equations automatically.
