Top: the centred age smooth on the log-odds scale, with the confidence band drawn by mgcv. The dashed line at zero is “age does nothing”, and it just about stays inside the band. Bottom: the fitted probability. The dashed line is a logistic regression that is linear in age, and it cannot come back down.
