Hi - A few comments on the problem set.
Some people seem to be having some trouble with functions.
I put some notes on functions in the FAQ, under programming. Please check that out along with the class notes if you are having trouble with functions. Many histogram plots I looked at used 50 or 20 bins for plotting. In case there is some confusion about this, the number of bins used does not have to equal the number of days in the simulation or the number of replicates. One more general programming comment.
