WebMay 4, 2024 · For example, suppose you have a smooth term s(x) with edf being 13.2, then we round it to 14. fit a new GAM without penalization, by setting fx = TRUE in all s() or te(). However, we now want to set k, the basis dimension to be the integers in the last step, plus one! Taking the example above, we want s(x, k = 15, fx = TRUE). Webgamm4 follows the approach taken by package mgcv and represents the smooths using penalized regression spline type smoothers, of moderate rank. For estimation purposes …
