Determination of the optimal number of strata for bias reduction in propensity score matching.

Akers, Allen - 2010

Previous research implementing stratification on the propensity score has generally relied on using five strata, based on prior theoretical groundwork and minimal empirical evidence as to the suitability of quintiles to adequately reduce bias in all cases and across all sample sizes. This study...

Too Much Ado about Instrumental Variable Approach: Is the Cure Worse than the Disease?

Baser, Onur - 2009

instruments may produce inconsistent and inefficient results. Methods: We use two IVs and apply Shea's partial R -square method …, the Anderson canonical correlation, and Cragg–Donald tests to check for weak instruments. Hall–Peixe tests are applied to … see if any of these instruments are redundant in the analysis. Results: A total of 14,952 asthma patients from the …

Nonparametric Bayes Conditional Distribution Modeling With Variable Selection

Dunson, David - 2009

This article considers a methodology for flexibly characterizing the relationship between a response and multiple predictors. Goals are (1) to estimate the conditional response distribution addressing the distributional changes across the predictor space, and (2) to identify important predictors...

Cost-efficient Variable Selection Using Branching LARS

Yue, Li Hua - 2010

Variable selection is a difficult problem in statistical model building. Identification of cost efficient diagnostic factors is very important to health researchers, but most variable selection methods do not take into account the cost of collecting data for the predictors. The trade off between...

Some Identification Issues in Nonparametric Linear Models with Endogenous Regressors

Severini, Thomas A.; Tripathi, Gautam - 2005

In applied work economists often seek to relate a given response variable y to some causal parameter mu* associated with it. This parameter usually represents a summarization based on some explanatory variables of the distribution of y, such as a regression function, and treating it as a...

Ownership, Control and Corporate Performance After Large-Scale Privatization

Hanousek, Jan; Ko?enda, Evžen; Svejnar, Jan - 2004

We analyze the effects of ownership type and concentration on performance of a population of firms in a model large-scale privatization economy (Czech Republic). Using specifications based on first-differences and unique instrumental variables, we find that few types of private ownership improve...
