WebApr 13, 2024 · I used spline functions (variable "time", 7 nodes) as an interaction term to model the different mortality trend over time of the 3 provinces. I'm having a hard time figuring out how to interpret the interaction coefficients. For example, I understand that compared to the period of time 1 (the period before the first knot, 18 days) the ...
