Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：The Use of Machine Learning in Treatment Effect Estimation
机器学习 治疗效果 估计
2023/5/8
We present recent developments in double machine learning (DML) approach. The DML approach is concerned primarily with selecting the relevant control variables and functional forms necessary for the c...
Ionogram inversion F1-layer treatment effect in raytracing
raytracing F1 region electron densityprofile
2015/9/10
This paper shows the importance of the F1-layer shape in the electron density profiles obtained from ionograms
with different inversion techniques when the profiles are used in ray tracing. This laye...
Estimating treatment effect heterogeneity in randomized program evaluation
Causal inference individualized treatment rules LASSO moderation variable selection
2013/6/14
When evaluating the efficacy of social programs and medical treatments using randomized experiments, the estimated overall average causal effect alone is often of limited value and the researchers mus...
Please Call Again: Correcting Non-Response Bias in Treatment Effect Models
survey non response sample selectivity treatment effect model randomized controlled trial
2012/10/23
We propose a novel selectivity correction procedure to deal with survey attrition, at the crossroads of the "Heckit" and of the bounding approach of Lee (2009). As a substitute for the instrument need...
Cereal-forage crop rotations and irrigation treatment effect on water use efficiency and crops sustainability in Mediterranean environment
Alfalfa Binary Mixture Durum Wheat lrrigation
2013/2/27
Agricultural systems based on crop rotations favour sustainability of cultivation and productivity of the crops. Wheat-forage crops rotations (annual winter binary mixture and perennial alfalfa meadow...
Thermal treatment effect on dynamics of luminescent states in oxyfluoride glass-ceramics doped with Pr3+ and Tb3+
oxyfluoride glasses differential thermal analysis thermal treatment optical properties luminescence dynamics lifetimes
2011/5/6
The 50GeO2–(50–x–y)PbO–yPbF2–xLnF3 glass single doped with Pr3+ and Tb3+ ions was
studied. The composition of the material was modified by varying the content of both PbF2 ( y = 5,
10, 15 mol%) and ...
The Treatment Effect of Mandibular Protrusive Appliances on the Glenoid Fossa for Class II Correction
Mandibular protrusive appliances Glenoid fossa reaction
2008/12/8
A study was undertaken to determine the contribution of glenoid fossa modification in the correction of skeletal Class II malocclusions. Individually corrected lateral tomograms of 35 patients (18 b...
