I am curious if anyone out there using ms() to do non-linear
fits knows how to find out standard errors for the estimated
parameters. The nls() function gives them as output, but
I can't find anything in the manuals about calculating these
for ms().
Also, does anyone have an example of specifying the analytical
forms of the first and second derivatives of the formula used
in ms(), specifically ones that require multiple partial
derivatives, so I can hack from there? Thanks for any help.
