Anybody who has taken even an introductory statistics course should be able to point out the egregious errors in this "analysis."
Have you taken an introductory statistics course? Can you help me see the egregious errors?
That's what I asked for in the OP.
That's why we can't use data from old primaries to predict data from new primaries.
This primary is different...It's basically been a race to see if they can find someone else besides Romney..

In the case of this analysis' methodology that's not true. The way they inputted data was based on a precinct's population size. As a result as you go on each data point is going to have a greater impact on the plot as a whole. So if a candidate does better in more densely populated areas you can expect a slope like the one we see. One of the major problems with this analysis is that they assume people in all precincts are going to vote in a similar manner. This simply isn't true. Each precinct is independent and a number of factors unique to that precinct can affect who they favor.
A key fact that must be remembered is that we are primarily comparing small precincts with large precincts. The majority of the population is moderate. As a result as population increases we can expect the number of vote for the most moderate to increase. In this case that is Romney.

I believe your wrong. If I'm not mistaken, the graphs shown listed the counties by ALPHABETICAL order, not precinct size. Your confusing this study with the one in the previous thread about South Carolina, but clearly that doesn't apply.

This is exactly what this analysis is doing.
The first graph in the OP shows it by alphabetical order in an attempt to show that the candidates lines go "flat" once the majority of the vote is counted. Then he re-orders it by precinct size to show, expectantly, that when you count the small precincts first that there is no flat slope.
It is exactly what he did with the SC vote.

Without knowing it you've actually brought up the very point we've been trying to make. The reason scientific theories are valid is because they control for every variable that is not being tested. As a result they can say X causes Y (unless they're doing a regression study, in which case they can say X is correlated to Y). There's none of that going on with these election analyses. They make the assumption that the variables they are not accounting for remain the same. This simply isn't true. That's why we can't use data from old primaries to predict data from new primaries.

Personal Disclosure: Just at a glance that last chart in the OP is BOGUS! My dad worked as HEAD of IT dept for Australian Bereau of Statistics and I am completely sure he would agree with me!
Bumping this thread for JUSTICE [who is blind and needs to loose the blindfold ok] !!!

Draco...
I believe you may have missed the point of OL's post.
He is agreeing that the stats look bogus. Not that the analysis is bogus.
Either way, is it really necessary to try and berate someone and downplay what their father does for a living?
It was extremely rude to make personal comments about him and/or his father.
Do you care to comment on the OP?

Ok, I see now where he does indeed switch. Thanks for clearing that up with me. (I even double checked before posting but still missed it, I blame it on midday PBR consumption).
I still think that as I discussed on the SC thread that this doesn't disqualify the study, and if you like you could read my last posts there, but I won't rehash it unless someone asks me (or I get bored).
