There are many different kinds of splines. Perhaps the most common
are B-splines, which sum to 1 inside their range of definition

Hello-
I am trying to model infections counts over 120 months using a GLM in R.
The model is simple really including a factor variable for year (10 yrs in
total) and another variable consisting of a natural spline function for time
in months.
My code for the GLM is as follows:
Plot the predictions; you can almost never interpret the coefficients
of a spline fit individually. They are not really independent or
separately interpretable.
Is this homework?
