. >> what are your thoughts on our lichtman -- on alan lichtman, academics like him who have these, what, 13 bases, or? dr. young: his keys? it's a model. it's a model that i don't understand 100% but i think it is a bit of take about how he measures things. there is a measurement issue. only he knows how to use the keys, it seems. if he can't open up the method from a scientific perspective and locate it then we have a problem. just as an aside i teach another class at some other places i am forecasting. what we do is we take the last electoral cycle and decompose all the models and recompose them. because they are transparent so we know how they are put together. we can take them apart and put them back together and figure out is wrong. there's not a lot of transparency there. i don't know how he is measuring variables. but he has some sort of probabilistic model so it is no different. there is no special sauce. it is like any other model that exists. it has an outcome which is the election and a series of other variables. his are mostly structural. but i do not think there is a lot of
