Non-linear regression problem: R vs JMP (long)
...ce in R despite starting from the estimates reported in JMP.
What can I do?
Full story:
I am collaborating on a project which presently requires the fit of a seven
parameter non-linear function to 874 observations. The function is:
freeze.d <- deriv3(~ dbh^b * u^dbh * a1 * smi^a2 * exp(a3*pbal) *
(1 + a4*exp(a5*ba)) * cr^a6 * dh5^a7,
c("a1","a2","a3","a4","a5","a6","a7","b","u"),
function(dbh, smi, pbal, ba, cr, dh5, a1, a2, a3, a4, a5, a6, a7, b, u){})
The dbh, smi, pbal, ba, cr, and dh5, ar...
