%description
Provides tools for classical parameter estimation of adsorption isotherm
models, including both linear and nonlinear forms of the Freundlich,
Langmuir, and Temkin isotherms. This package allows users to fit these
models to experimental data, providing parameter estimates along with fit
statistics such as Akaike Information Criterion (AIC) and Bayesian
Information Criterion (BIC). Error metrics are computed to evaluate model
performance, and the package produces model fit plots with bootstrapped
95%% confidence intervals. Additionally, it generates residual plots for
diagnostic assessment of the models. Researchers and engineers in material
science, environmental engineering, and chemical engineering can
rigorously analyze adsorption behavior in their systems using this
straightforward, non-Bayesian approach. For more details, see Harding
(1907) <doi:10.2307/2987516>.
