Dear All,
I am trying to fit the following model in nlsLM():
fn5 - function(x, T, t1, w_inf, Lt0){
S-function(x, T, t1){
x+(1-T)/(2*pi)*sin(2*pi*(x-t1)/(1-T))
}
F - function(x, T, t1){
t2 - t1 + (1-T)/2
t3 - t1 + (1+T)/2
t.factorial - x%%1
floor(x)*(1-T) + S(t.factorial, T, t1)*(0=t.factorial
Suitable help may not be possible. I suspect that either your
function/code is funky (is the function smooth, non-infinite near your
starting value?) or you are overparameterized. If the latter, the
remedy may depend on the nature of your data, which you have not
shared.
