A list of interesting R/Stats quickies to keep the mind distracted: A long draft Advanced Data Analysis from an Elementary Point of View by Cosma Shalizi, in which he uses R to drive home the message. Not your average elementary point of view. Good notes by Frank Davenport on starting using R with data from […]

This seems to be the topic of the week. Yesterday I posted on the sister blog some further thoughts on those “Psychological Science” papers on menstrual cycles, biceps size, and political attitudes, tied to a horrible press release from the journal Psychological Science hyping the biceps and politics study. Then I was pointed to these [...]The post How to fix the tabloids? Toward replicable social science research appeared first on…

Here are comments by Olli following my post: I think we found a general means to obtain accurate ABC in the sense of matching the posterior mean or MAP exactly, and then minimising the KL distance between the true posterior and its ABC approximation subject to this condition. The construction works on an auxiliary probability […]

Matt Brigg’s comment on outliers in his post Tyranny of the mean: Coontz used the word “outliers”. There are no such things. There can be mismeasured data, i.e. incorrect data, say when you tried to measure air temperature but your thermometer fell into boiling water. Or there can be errors in recording the data; transposition […]

Anirban Bhattacharya, Debdeep Pati, Natesh Pillai, and David Dunson write: Penalized regression methods, such as L1 regularization, are routinely used in high-dimensional applications, and there is a rich literature on optimality properties under sparsity assumptions. In the Bayesian paradigm, sparsity is routinely induced through two-component mixture priors having a probability mass at zero, but such [...]The post Infill asymptotics and sprawl asymptotics appeared first on Statistical Modeling, Causal Inference, and…

I will be at Book Expo this Friday signing books at the McGraw-Hill booth. If you're in NYC, drop by and say hi between 11 and 12. Yes, it's a new book! The title is Numbersense: How to Use Big Data to Your Advantage (link). If you read my blogs, you already know where I'm going with this. How can we be smart consumers of data analyses in a world…

The power of a statistical test measures the test's ability to detect a specific alternate hypothesis. For example, educational researchers might want to compare the mean scores of boys and girls on a standardized test. They plan to use the well-known two-sample t test. The null hypothesis is that the [...]

There has been a lot of discussion among statisticians about big data and what statistics should do to get involved. Recently Steve M. and Larry W. took up the same issue on their blog. I have been thinking about this … Continue reading →

Paul Alper writes: Unless I missed it, you haven’t commented on the recent article of Michael Bang Peterson [with Daniel Sznycer, Aaron Sell, Leda Cosmides, and John Tooby]. It seems to have been reviewed extensively in the lay press. A typical example is here. This review begins with “If you are physically strong, social science [...]The post Another one of those “Psychological Science” papers (this time on biceps size and…

True story (no really, this did actually happen). While in grad school one of the other teaching assistants was approached by one of the students and was asked “will mu go out with median?” The teaching assistant thought the play on words was pretty funny, laughed, and then cluelessly walked away. All of us other grad students […]

Almost once every year someone asks if R has a package for running the MaxDiff procedure sold by Sawtooth. One such inquiry recently received a reply with a link showing in some detail the R code needed to generate a balanced incomplete...

Aggressive, fizzing nonconformity. The post Escalatingly uncomfortable appeared first on Statistical Modeling, Causal Inference, and Social Science.

Saw Argo the other day, was impressed by the way it was filmed in such a 70s style, sorta like that movie The Limey or an episode of the Rockford Files. I also felt nostalgia for that relatively nonviolent era. All those hostages and nobody was killed. It’s a good thing the Ayatollah didn’t have [...]The post Nostalgia appeared first on Statistical Modeling, Causal Inference, and Social Science.
