Your command should have yielded this:
?FindFit Using the first form given above, the first argument we need to give it is our list of census data, the second is the form of the function we're using for our model, (in our case Malthus or Verhulst,), the third argument is our parameters, and the fourth is our variable, (in our case Let's give it a shot. We'll create and name our Malthusian modeling function with the following command, (go ahead and enter it now, then come back.) usmalthusfit = p0*E^(k t) This is the classic form of the Malthusian model that you'll find in most books. You'll notice that it is slightly different, and somewhat simpler than the form we got when we had FindFit[uscensus, usmalthusfit, {p0, k}, t] Let's move on to discuss what just happened... |
