Causal Inference with Two-Stage Logistic Regression - Accuracy, Precision, and Application
Cai, Bing - 2010
2SPS and 2SRI for logistic binary outcomes have not been thoroughly studied. We study the bias and variance properties … trial. We first present closed form expressions of asymptotic bias for the causal odds ratio from both 2SPS and 2SRI … approaches. Our closed form bias results show that the 2SPS logistic regression generates asymptotically biased estimates of this …

The Impacts of Attribute Level Framing and Changing Cost Levels on Choice Experiments Value Estimates
Kragt, Marit Ellen; Bennett, Jeffrey W. - 2010
Choice Experiments (CE) are increasingly used to estimate the values of environmental goods andservices. CE questionnaires represent the environmental good under valuation by varying levels ofnon-market attributes. Inclusion of a cost attribute enables the estimation of monetary values...

Adaptive Inference for Multi-Stage Survey Data
Al-Zou'bi, L. M.; Clark, Robert Graham; Steel, D. G. - 2009
Two-stage sampling usually leads to higher variances for estimators of means and regression coefficients, because of intra-cluster homogeneity. One way of allowing for clustering in fitting a linear regression model is to use a linear mixed model with two levels. If the estimated intra-cluster...
