From: Jeff <jeffscofield@ucla.edu> To: Teacher2Teacher Public Discussion Date: 2004100814:42:48 Subject: Re: Project For that I would start with a simple symbiosis model. Look at the classics: May's Stability and Complexity in Model Eco Systems or even just look at some of the examples in Goldbergs Difference Equations book. For your questions, difference equations probably are overkill, as the relation can be modeled with the equation for a line. Here, the slope is the increase in democratic identification as education increases. If you want to do a really nice model you would do the more complex relationship that political science shows: increasing education increases chance of voting Dem. Increasing education increases income. Increasing income DECREASES chance of voting Dem. (Which is why there are a lot of highly educated Repubs, but that is the income/class effect; the education effect works in reverse.) This will require a two equation model using differential or difference equations. The choice is probably not important. Good Luck.
