error estimating parameters with mle2
...data5)
I get following error message
Error in optim(par = c(4.5, 0.16), fn = function (p) :
function cannot be evaluated at initial parameters
Can someone tell me what I'm doing wrong? I used estimate starting values
which were predicted with the nls function
RogersI_N <-
nls(FR~attackR2_N+u_N*N0,start=list(attackR2_N=1,u_N=4),control=list(maxiter=10000))
For some other models, I do the exact same thing and it works well, so I
don't understand why this one doesn't work........................
Kind regards,
Met vriendelijke groeten,
