Excel can do what R can't?????
...with it, and if
you come up with something, PLEASE let me know- In the meantime, I've got
to start fiddling with excel and figuring out how to automate the solver
calculation.....
Briefly, the point of the program is to approximate the model output from
an iterative calculation, Wtmod and Hgtmod, to user-specified endpoints Wt
and Hgt, by seeking the optimal values of p, ACT involved in the iterative
process.
Also, if your interested in recent correspondence that explains the point
of the program a bit, and how the function ties in to the iterative
process, search the R help forum for...
