I have two questions regarding loess procedures. 1) How does one best
produce a graph of a loess where the y-axis variable is binomial (e.g.
viral suppression v. no viral suppression) and the x-axis is time; 2)
How can one produce confidence intervals around the loess curve? 
I would appreciate any help on this.
Cheers,
