Andy's Brain Blog: Conjunction Analysis in AFNI

If we have one statistical map for Contrast A and another map for Contrast B, we could ask whether there are any voxels common to both A and B. First, we have to ask ourselves, "Why are we in academia? Note that the heaviest degree of overlap, here around the DLPFC region, is what passes the conjunction analysis. For more than two contrasts. If you have more...

Friday, 4 October 2013. In the last edition of Significance Magazine. Discusses the how efficient part. The so called relentless logic is covered in details in this book. And commented in the article. The "relentless" part comes from the fact that the idea is to transform the results of the actions of the organization into money, or quantify it using currency values, which is sort of disgusting. But anyway, the argument is that it is valid if it leads to better use of the received funds. President-elect ...

http://discoverstat.blogspot.com/2013/07/confidence-intervals-through-simulation.html
Wednesday, 3 July 2013. Confidence Intervals through simulation. A paper that appeared in the last edition of The American Statistician. So, it often happens that one needs to estimate these intervals for functions of parameters. For example, in a recent study we needed to estimate the effect in percent in a Regression Discontinuity model. Basically we wanted a confidence interval for the ratio of two regression coefficients.
