Statistical Matching of Administrative and Survey Data: An Application to Wealth Inequality Analysis 23 Aug 2013 | 01:23 pm
Using population representative survey data from the German Socio-Economic Panel (SOEP) and administrative pension records from the Statutory Pension Insurance, the authors compare four statistical ma...
Total, Direct, and Indirect Effects in Logit and Probit Models 23 Aug 2013 | 01:23 pm
This article presents a method for estimating and interpreting total, direct, and indirect effects in logit or probit models. The method extends the decomposition properties of linear models to these ...
Under What Assumptions Do Site-by-Treatment Instruments Identify Average Causal Effects? 23 Aug 2013 | 01:23 pm
The increasing availability of data from multisite randomized trials provides a potential opportunity to use instrumental variables (IV) methods to study the effects of multiple hypothesized mediators...
Ceilings and Floors: Where Are There No Observations? 12 Jan 2013 | 04:24 am
There are situations where the data or the theory suggest or require, respectively, that one estimate the boundary lines that separate regions of observations from regions of no observations. Of parti...
The Duality of Clusters and Statistical Interactions 12 Jan 2013 | 04:24 am
We contend that clusters of cases co-constitute statistical interactions among variables. Interactions among variables imply clusters of cases within which statistical effects differ. Regression coeff...
Combining Statistical Evidence From Several Studies: A Method Using Bayesian Updating and an Example From Research on Trust Problems in Social and Eco... 12 Jan 2013 | 04:24 am
The effect of an independent variable on a dependent variable is often evaluated with hypothesis testing. Sometimes, multiple studies are available that test the same hypothesis. In such studies, the ...
Evaluating Relative Mode Effects in Mixed-Mode Surveys:: Three Methods to Disentangle Selection and Measurement Effects 12 Jan 2013 | 04:24 am
In order to investigate the advantage of mixed-mode (MM) surveys, selection effects between the modes should be evaluated. Selection effects refer to differences in respondent compositions on the targ...
Should a Normal Imputation Model be Modified to Impute Skewed Variables? 12 Jan 2013 | 04:24 am
Researchers often impute continuous variables under an assumption of normality–yet many incomplete variables are skewed. We find that imputing skewed continuous variables under a normal model can lead...
ML Versus MI for Missing Data With Violation of Distribution Conditions 25 Oct 2012 | 12:39 am
Normal-distribution-based maximum likelihood (ML) and multiple imputation (MI) are the two major procedures for missing data analysis. This article compares the two procedures with respects to bias an...
Distinguishing Between Cross- and Cluster-Level Mediation Processes in the Cluster Randomized Trial 25 Oct 2012 | 12:39 am
For the cluster randomized trial, the treatment, implemented at the cluster level, may be hypothesized to impact a final outcome of interest via a mediating variable, with the mediator and outcome bei...
