“What then should we teach about hypothesis testing?”

January 24, 2015
By

Someone who wishes to remain anonymous writes in: Last week, I was looking forward to a blog post titled “Why continue to teach and use hypothesis testing?” I presume that this scheduled post merely became preempted by more timely posts. But I am still interested in reading the exchange that will follow. My feeling is […] The post “What then should we teach about hypothesis testing?” appeared first on Statistical…

A bunch of papers

The beginning of the new year has been particularly busy, as I'm working on several interesting projects. On the bright side, some of these are starting to give their fruits and, coincidentally, in the last few days we've had a few papers finalise...

Cross-validation, LOO and WAIC for time series

January 16, 2015
By

This post is by Aki. Jonah asked in Stan users mailing list Suppose we have J groups and T time periods, so y[t,j] is the observed value of y at time t for group j. (We also have predictors x[t,j].) I’m wondering if WAIC is appropriate in this scenario assuming that our interest in predictive accuracy is for […] The post Cross-validation, LOO and WAIC for time series appeared first on Statistical Modeling,…

Stan comes through . . . again!

Erikson Kaszubowski writes in: I missed your call for Stan research stories, but the recent post about stranded dolphins mentioned it again. When I read about the Crowdstorming project in your blog, I thought it would be a good project to apply my recent studies in Bayesian modeling. The project coordinators shared a big dataset […] The post Stan comes through . . . again! appeared first on Statistical Modeling,…

Planning my class for this semester: Thinking aloud about how to move toward active learning?

January 9, 2015
By

I’m teaching two classes this semester: - Design and Analysis of Sample Surveys (in the political science department, but the course has lots of statistics content); - Statistical Communication and Graphics (in the statistics department, but last time I taught it, many of the students were from other fields). I’ve taught both classes before. I […] The post Planning my class for this semester: Thinking aloud about how to move…

There’s something about humans

January 5, 2015
By

An interesting point came up recently. In the abstract to my psychology talk, I’d raised the question: If we can’t trust p-values, does experimental science involving human variation just have to start over? In the comments, Rahul wrote: Isn’t the qualifier about human variation redundant? If we cannot trust p-values we cannot trust p-values. My […] The post There’s something about humans appeared first on Statistical Modeling, Causal Inference, and…

Advance notice

As a few people have already inquired (more or less formally) about the next edition of the short course on Bayesian Methods in Health Economics, I thought it would be nice to start the new year off by posting some details on that...While we're explori...

“Why continue to teach and use hypothesis testing?”

January 3, 2015
By

Greg Werbin points us to an online discussion of the following question: Why continue to teach and use hypothesis testing (with all its difficult concepts and which are among the most statistical sins) for problems where there is an interval estimator (confidence, bootstrap, credibility or whatever)? What is the best explanation (if any) to be […] The post “Why continue to teach and use hypothesis testing?” appeared first on Statistical…

The Use of Sampling Weights in Bayesian Hierarchical Models for Small Area Estimation

December 19, 2014
By

All this discussion of plagiarism is leaving a bad taste in my mouth (or, I guess I should say, a bad feeling in my fingers, given that I’m expressing all this on the keyboard) so I wanted to close off the workweek with something more interesting. I happened to come across the above-titled paper by […] The post The Use of Sampling Weights in Bayesian Hierarchical Models for Small Area…
