A solution to a class of selection-bias problems
In a recent article (Pearl, 2012), I posed a series of questions to econometricians, to demonstrate how long-standing problems in econometric research can be resolved using modern techniques of causal analysis. Among the questions were three pertaining to sample selection bias, to which this paper provides a general solution. The original questions are presented in Section 2.1, their solutions ...
متن کاملInnovativeness of software solutions: evidence from an alternative methodology Comparing Free/Open Source and proprietary products
The issue of innovation processes taking place in the software sector is currently widely debated. Challenging questions arise about what products/services have to be considered innovative, and whether a specific artefact is innovative or not. In this framework, the widespread success of the Free/Open Source Software (FOSS) put forward new research issues, dealing with whether and how programs ...
متن کاملHydraulic fracture propagation: analytical solutions versus Lattice simulations
In this work, we used a grain-based numerical model based on the concept of lattice. The modelling was done to simulate the lab experiments carried out on the mortar samples. Also the analytical solutions corresponding to the viscosity-dominated regime were used to estimate the fracture length and width, and the results obtained were compared with the numerical simulations. As the analytical so...
متن کاملReconsideration of Potential Problems of Applying EMIM for Text Analysis
It seems that the term dependence methods developed using the expected mutual information measure (EMIM) have not achieved their potential in many areas of science, involving statistical text analysis or document processing. This study examines the reasons for the failure and highlights potential problems of applications. Several interesting questions are arisen, including, does a term provide ...
متن کاملRecent advances in quantitative LA-ICP-MS analysis: challenges and solutions in the life sciences and environmental chemistry
Laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) is a widely accepted method for direct sampling of solid materials for trace elemental analysis. The number of reported applications is high and the application range is broad; besides geochemistry, LA-ICP-MS is mostly used in environmental chemistry and the life sciences. This review focuses on the application of LA-ICP-MS...
