mgcv
. It is a modification
of the function glm.control
. It enables the user to set defaults for convergence
tolerance and maximum number of iterations when using
gam
. Argument mgcv.tol
controls the tolerence used to judge
multiple smoothing parameter convergence (default 1e-6). mgcv.max.half
is the
maximum number of times to halve the step length in an iterative update of the
smoothing parameters if the step is failing to decrease the GCV/UBRE
score (default 15). See glm.control
for more information on other arguments.Wood (2000) Modelling and Smoothing Parameter Estimation with Multiple Quadratic Penalties. JRSSB 62(2):413-428
