Fig. 3: Graphical representation of prediction of uptake with respect to level of deprivation.
From: Long-term spatial patterns in COVID-19 booster vaccine uptake
For each cohort, the green box bounds the floor and ceiling values of deprivation rank shift Δ. Within this range, the projected uptake (blue points) falls for decreasing Δ (increasing level of deprivation). A sigmoid function (black, dotted) is fit to these fit values, which is then shifted to match the actual returning first booster uptake (red circle) at Δ = 0 (vertical dashed line).
