Unifying Political Methodology: The Likelihood Theory of Statistical Inference

. Ann Arbor: University of Michigan Press. Publisher's Version# Unifying Statistical Analysis

Development of a unified approach to statistical modeling, inference, interpretation, presentation, analysis, and software; integrated with most of the other projects listed here.

## Unifying Approaches to Statistical Analysis

Sets out the general framework. . 1998.

A generalization of Clarify, and much other software, implemented in R. The extensive manual encompasses most of the above works and can be read independently as an introduction to wide range of models. Under active development. . 2006. “Zelig: Everyone's Statistical Software”. Publisher's Version

Generalizes the unification in the book (replacing its Section 5.2 with simulation to compute quantities of interest). This paper, which was originally titled "Enough with the Logit Coefficients, Already!", explains how to compute any quantity of interest from almost any statistical model; and shows, with replications of several published works, how to extract considerably more information than standard practices, without changing any data or statistical assumptions. . 2000. “Making the Most of Statistical Analyses: Improving Interpretation and Presentation.” American Journal of Political Science 44: 341–355.
