Response to “Best (but oft forgotten) practices: testing for treatment effects in randomized trials by separate analyses of changes from baseline in each group is a misleading approach”
treatment effect randomized trial misleading approach
2018/11/28
We were surprised to see our study (1) used as the first example of how not to compare group means with each other in the recent article by Bland and Altman (2), because, in fact, our conclusions were...
Qualitative implication and equivalence relations between treatment effects on surrogates and endpoints
Causal effect Prentice’s criterion Surrogate endpoint
2016/1/19
By the criterion for surrogates proposed by Prentice (1989), a null treatment effect on a surrogate implies a null treatment effect on a true endpoint.In this paper, we show that there may exist simul...
Estimating Heterogeneous Treatment Effects of Medicaid Expansions on Take-up and Crowd-out
Medicaid expansions take-up crowd-out treatment effects switching probit model random coefficient models linear probability models counterfactual policy analysis
2015/9/18
Economists have devoted considerable resources to estimating local average treatment effects of expansions in Medicaid eligibility for children. In this paper we use random coefficients linear probabi...
Poststroke depression and treatment effects on functional outcomes

Adjusting for Treatment Effects in Studies of Quantitative Traits
Quantitative traits Imputation QTL mapping Single-marker analysis Mixed models Kruskal-Wallis test
2013/6/14
A population-based study of a quantitative trait, e.g. Blood Pressure(BP) may be seriously compromised when the trait is subject to the effects of a treatment. Without appropriate corrections this can...

Bounds on Average and Quantile Treatment Effects of Job Corps Training on Wages
Bounds on Average Quantile Treatment Effects Job Corps Training Wages
2016/3/9
We review and extend nonparametric partial identification results for average and quantile treatment effects in the presence of sample selection. These methods are applied to assessing the wage effect...
The importance of distinct modeling strategies for gene and gene-specific treatment effects in hierarchical models for microarray data
Diffierential expression EM algorithm hierarchical models random effects uncertainty
2012/11/23
When analyzing microarray data, hierarchical models are often used to share information across genes when estimating means and variances or identifying differential expression. Many methods utilize so...
Measuring direct and indirect treatment effects using safety performance intervention functions
Intervention models Full Bayes estimation Poisson–lognormal regression Random parameters models Treatment effectiveness index
2012/4/14
Recent traffic safety research has advocated the use of the Full Bayes (FB) approach to conduct controlled before–after safety evaluations. The FB approach was shown to offer both methodological and d...
Bounds on Average and Quantile Treatment Effects of Job Corps Training on Wages
