Interval arithmetic: Fundamentals, Successes and Pitfalls

Interval arithmetic: Fundamentals, Successes and Pitfalls. Ralph Baker Kearfott Professor Applied Mathematics, University of Louisiana, Lafayette, Louisiana USA. Julio 27 de 2018. Abstract: In this tutorial survey, we introduce the underlying motivations for interval arithmetic, along with the basic operations. We give a history of interval arithmetic, we highlight notable successes in scientific and engineering problems, and we...

Topología

Topología El término topología se utiliza para identificar a un área de la matemática que estudia la continuidad y otros conceptos originados a partir de ella. Se trata de una especialización vinculada a las propiedades y características que poseen los cuerpos geométricos y que se mantienen sin alteraciones gracias a cambios continuos, con independencia de su tamaño o apariencia. Las funciones continuas de la matemática son aquellas...

Oaxaca-Blinder Type Counterfactual Decomposition Methods for Duration Outcomes

Oaxaca-Blinder Type Counterfactual Decomposition Methods for Duration Outcomes. Andrés Felipe García-Suaza Abstract: Existing inference procedures to perform counterfactual decomposition of the difference between distributional features, applicable when data is fully observed, are not suitable for censored outcomes. This may explain the lack of decomposition exercises for variables related to duration outcomes, typically observed...
