A solution to a class of selection-bias problems
نویسنده
چکیده
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 in Section 2.2, and further generalizations are then developed in Section 3.

Existence of positive solution to a class of boundary value problems of fractional differential equations
This paper is devoted to the study of establishing sufficient conditions for existence and uniqueness of positive solution to a class of non-linear problems of fractional differential equations. The boundary conditions involved Riemann-Liouville fractional order derivative and integral. Further, the non-linear function $f$ contain fractional order derivative which produce extra complexity. Than...

Integration of production planning and scheduling is a class of problems commonly found in manufacturing industry. This class of problems associated with precedence constraint has been previously modeled and optimized by the authors, in which, it requires a multidimensional optimization at the same time: what to make, how many to make, where to make and the order to make. It is a combinatorial,...

متن کاملComputationally Efficient Class-Prior Estimation under Class Balance Change Using Energy Distance
In many real-world classification problems, the class balance often changes between training and test datasets, due to sample selection bias or the non-stationarity of the environment. Naive classifier training under such changes of class balance systematically yields a biased solution. It is known that such a systematic bias can be corrected by weighted training according to the test class bal...
متن کاملA numerical technique for solving a class of 2D variational problems using Legendre spectral method
An effective numerical method based on Legendre polynomials is proposed for the solution of a class of variational problems with suitable boundary conditions. The Ritz spectral method is used for finding the approximate solution of the problem. By utilizing the Ritz method, the given nonlinear variational problem reduces to the problem of solving a system of algebraic equations. The advantage o...
