Totally disagree. The diary was a 40 year farse. The fat and moronic weighting for minorities is what most, including you, are crying about.
The only weighting, ever, in the diary method is up or down weighting to bring a cell into proportionality in the market. That includes weighting of each diary for age cell, geographic division, gender, and ethnicity / language dominance if the last two apply.
There is no weighting, nor has there been, any weighting that makes any ethnic group look better than reality.
The often higher than average returns of diaries by Hispanics overall meant that many diaries were actually weighted down, not up. The highest upward weighting occurs in the diary for 18-24 and 25-34 non-ethnic men.
There was no dispropotionate weighting on any stratification variable in the LA diary survey, or, for that matter, in any other market. You are, by making that vastly untrue statement (highlighted in blue above) are perpetuating an urban legend.
It's true that DST was introduced about 30 years ago to make sure the ethnic and young adult male samples were proportional, but DST was basically made up of creating HDHA and HDBA zones and doing incentive increases for hard to get cells. There is no weighting there... in fact, DST reduced weighting.
Diaries, of which I filled out a nice household of and helped bump up all my favorite Los Angeles talkradio hosts during a survey period not to be named here, shows how idiotic it was.
How nice. You admit you cheated. If you worked for a radio station at the time, you violated their contract and, no doubt, their employee proceedures.
In any case, one diary out of 7500 in LA does not affect much, and Arbitron yanks lots of diaries after checking, via a flagging algorithm, for atypical individual or household behaviour.
The fact is that experts who know more than any of us on these boards, namely the MRC, have not accredited the LA PPM book and the diary based book was accredited. In fact, only one US market was not accredited in the diary survey.
