Model coefficients for parametric and smoothed terms included in the best performing model. These include the estimate (Est.), standard error (SE), t-statistic (t) and p-value (p) for parametric terms, and estimated degrees of freedom (EDF), reference degrees of freedom (RDF), F-statistic (F) and p for smoothed terms
