BREAKING THE LAW! (of likelihood): to keep their fit measures in line (A), (B 2nd)

1.An Assumed Law of Statistical Evidence (law of likelihood) Nearly all critical discussions of frequentist error statistical inference (significance tests, confidence intervals, p- values, power, etc.) start with the following general assumption about the nature of inductive evidence or support: Data x are better evidence for hypothesis H1 than for H0 if x are more probable under H1 than […]

Avoiding model selection in Bayesian social research

August 29, 2014

One of my favorites, from 1995. Don Rubin and I argue with Adrian Raftery. Here’s how we begin: Raftery’s paper addresses two important problems in the statistical analysis of social science data: (1) choosing an appropriate model when so much data are available that standard P-values reject all parsimonious models; and (2) making estimates and […] The post Avoiding model…
