@snsharma & Michael Elliott develop a method of detecting survey falsification. The method uses multilevel models & they illustrate its use in a panel survey in India measuring TV ratings https://t.co/9QjQ3yVphg

Some of the TV panels discussing exit polls are larger than the sample size :D

Super story to illustrate very clever use of technology and modeling - sadly, to defraud.

@yshendye I agree! For most people it comes as a total surprise in the 2nd year. And if you refuse, then the threats start.

Love it when technical books are interspersed with humor. This is from: "Measurement Error in Nonlinear Models", Carroll, Rupert, and Stefanski (2006). #Statistics

Nice preface in #Statistics (Freedman, Pisani, and Purves, 1998). But a bit surprised at the highlighted phrase.

(2/2) i.e. despite energy drain, may be publicly valuable to call out BS emanating from a celebrity vs. arguing online with 'agentsky9991'.
