Using optim function for logistic model simulation
...increasing again. I'm thinking that there are 3 different carrying capacity values, but my understanding of optim is that it can only optimize one parameter variable at a time. So I was going to take the brute force approach of artificially breaking up the equation into 3 parts (i.e. make eqn1, eqn2, and eqn3, and optimize each separately, with the input values for the later two functions coming from the last number of birds from the previous loop). Thank you all very much! charlotte
