November 12, 2010## Model Identification and Computer Algebra

November 12, 2010Kenneth A. Bollen and Shawn Bauldry, **Model Identification and Computer Algebra**, Sociological Methods & Research 2010 39: 127-156.

Multiequation models that contain observed or latent variables are common in the social sciences. To determine whether unique parameter values exist for such models, one needs to assess model identification. Read the rest of this entry »

## Assessing Group Differences in Estimated Baseline Survivor Functions From Cox Proportional Hazards Models

November 12, 2010Daniel A. Powers, **Assessing Group Differences in Estimated Baseline Survivor Functions From Cox Proportional Hazards Models**, Sociological Methods & Research 2010 39: 157-187.

The author discusses the general problem of evaluating differences in adjusted survivor functions and develops a heuristic approach to generate the expected events that would occur Read the rest of this entry »

## Proportional Reduction of Prediction Error in Cross-Classified Random Effects Models

November 12, 2010Wen Luo and Oi-Man Kwok, **Proportional Reduction of Prediction Error in Cross-Classified Random Effects Models**, Sociological Methods & Research 2010 39: 188-205.

As an extension of hierarchical linear models (HLMs), cross-classified random effects models (CCREMs) are used for analyzing multilevel data that do not have strictly Read the rest of this entry »

## An Alternative to the Bar-Lev, Bobovitch, and Boukai Randomized Response Model

November 12, 2010Oluseun Odumade and Sarjinder Singh, **An Alternative to the Bar-Lev, Bobovitch, and Boukai Randomized Response Model**, Sociological Methods & Research 2010 39: 206-221.

In this article, an alternative randomized response model is proposed. The proposed model is found to be more efficient than the randomized response model studied by Bar-Lev, Bobovitch, and Boukai (2004). Read the rest of this entry »

## Latent Markov Model for Analyzing Temporal Configuration for Violence Profiles and Trajectories in a Sample of Batterers

November 12, 2010Edward H. Ip, Alison Snow Jones, D. Alex Heckert, Qiang Zhang and Edward D. Gondolf, **Latent Markov Model for Analyzing Temporal Configuration for Violence Profiles and Trajectories in a Sample of Batterers**, Sociological Methods & Research 2010 39: 222-255.

In this article, the authors demonstrate the utility of an extended latent Markov model for analyzing temporal configurations in the behaviors of a sample of 550 domestic violence batterers. Read the rest of this entry »

## A Cautionary Note on the Use of Matching to Estimate Causal Effects: An Empirical Example Comparing Matching Estimates to an Experimental Benchmark

November 12, 2010Kevin Arceneaux, Alan S. Gerber, and Donald P. Green, **A Cautionary Note on the Use of Matching to Estimate Causal Effects: An Empirical Example Comparing Matching Estimates to an Experimental Benchmark**, Sociological Methods & Research 2010 39: 256-282.

In recent years, social scientists have increasingly turned to matching as a method for drawing causal inferences from observational data. Matching compares those who receive a treatment to those with similar Read the rest of this entry »
