He’s a history teacher and he has a statistics question

Someone named Ian writes: I am a History teacher who has become interested in statistics! The main reason for this is that I’m reading research papers about teaching practices to find out what actually “works.” I’ve taught myself the basics of null hypothesis significance testing, though I confess I am no expert (Maths was never […]

An actual quote from a paper published in a medical journal: “The data, analytic methods, and study materials will not be made available to other researchers for purposes of reproducing the results or replicating the procedure.”

Someone writes: So the NYT yesterday has a story about this study I am directed to it and am immediately concerned about all the things that make this study somewhat dubious. Forking paths in the definition of the independent variable, sample selection in who wore the accelerometers, ignorance of the undoubtedly huge importance of interactions […]

Young Investigator Special Competition for Time-Sharing Experiment for the Social Sciences

Sociologists Jamie Druckman and Jeremy Freese write: Time-Sharing Experiments for the Social Sciences is Having A Special Competition for Young Investigators Time-sharing Experiments for the Social Sciences (TESS) is an NSF-funded initiative. Investigators propose survey experiments to be fielded using a nationally representative Internet platform via NORC’s AmeriSpeak Panel (see http:/tessexperiments.org for more information). While […]

Be clear about the information that goes into statistical procedures, 3. Create a culture of respect for data, 4. Publication of criticisms, 5. Respect the limitations of statistics. The full […]

Fitting the Besag, York, and Mollie spatial autoregression model with discrete data

Rudy Banerjee writes: I am trying to use the Besag, York & Mollie 1991 (BYM) model to study the sociology of crime and space/time plays a vital role. Since many of the variables and parameters are discrete in nature is it possible to develop a BYM that uses an Integer Auto-regressive (INAR) process instead of […]
