Hi, I have problems writing a script for a logistic model. My data looks something like this:
PI A N1 N2 N3 0 9 0 1 0 1 4 1 0 1 0 8 0 0 0 1 6 0 1 0 And so on… The model I want to fit looks like this: PI=exp^f(sw)/1+exp^f(sw) where f(sw)=c+(a1*N1/A^z)+(a2*N2/A^z)+(a3*N3/A^z) So I want to estimate c,a1,a2,a3 and z… Is there someone who can help me on this problem, because I don’t even know how to start.
