Displaying 1 result from an estimated 1 matches for "rotavirus".

mgcv, gam
...not the
main point.
I want to have a smooth term for time over a year, the same pattern
repeating in succesive years. It would be natural then to impose
the condition s(0)=s(12). Is this possible within mgcv?
I tried to obtain this with trigonometric terms, aca:
> Rot.gam2 <- gam(cbind(Rotavirus,Total)~ s( I(sin((MesN/12)*2*pi)),
bs="cr" )+
+ s( I(cos((MesN/12)*2*pi)), bs="cr" ),
data=na.omit(Rot),
+ family=binomial)
