Your command should have produced this result: malthus/.t->0 This new result seems almost as silly as FindFit's earlier estimate of 0. In fact how can there possibly have been this many people, as you can't have a fraction of a person like this? Well there are two reasons this is better than before. First, at least a non-zero value of p0 has the So to summarize, we're now going to try using FindFit again, but this time we will suggest that it start looking for a value of p0 near 10 FindFit[uscensus, usmalthusfit, {{p0, 10^-9}, {k, .02}}, t] Let's go see what you should have gotten... |
