Not a complaint, just an observation.

Yes, thats not a high crime on their part. If they found non violent
crimes went down dramatically, I am confident the summary of the study
would highlight non-violent crimes. Don't you? Really? Thats how
analysis under pressure works. Its what happens in the real world.
People make their best case. Not a high crime. But one needs to be
aware that the researchers here, as in many other places, had
incentives to look for answers that met sponsors desires and
expecatations. No different from 1000's of corporate analysts. And
100's of non-profit foundation analysts. But maybe you have to have
"been there" in various situations and cases to understand this.

Ok, if I have misunderstoood, please explain it to me. Though you
appear to attribute an agenda to me, I have none. I am trying to
understand both the data and the analysis.

OK.


Akasha's explanations are not on a level

I do my best, really, I do try to make it understandable. Think about
it. For me it would be a happier place if people understood some
basics of modeling, statistics and regression.

Sorry if it has not been apparent. Actually I wrote some posts,
detailing how regression works, with you in mind, Regardless, I am
happy to help you out in understanding any knowledge I might have
picked up along the way. Just ask, or perhaps be receptive to attempts
to share knowledge.

Well, its not magic. Based on a survey of available data, constraints
on such and all, I can speculate with some degree of reasonablness as
to what issues they faced, and how they approached the problems
methodologically. I have been there.
