Comparing smooths in factor-smooth interactions II

This time I look at how to use ordered factors w by-variable smooth, to fit a reference smooth plus difference smooths for the other levels

Simultaneous intervals for smooths revisited: correcting a silly mistake

New #rstats blog post in which I eat crow over an earlier post in which I claimed to generate a simultaneous confidence interval for a GAM but got it gob-smackingly wrong!
