Applications of R in Business Contest: 2012

shared by LaRuPu upv on 01 May 13 - No Cached
  • Here at Revolution Analytics, we’d like to thank all of the data scientists who participated in our first R in Business competition and congratulate the winners. Each of the applications selected demonstrates how predictive analytics with R goes well beyond traditional business intelligence to empower business decision-makers to evaluate critical success factors within important business processes early and often. We see from the winning entries that a wide variety of industries and processes – from marketing, heavy manufacturing, clinical trial design, and IT project management all share a need for ongoing predictive analysis. Revolution Analytics delivers the only R-based enterprise analytics framework, and by examining undiscovered applications of the R language, Revolution Analytics can further refine R tools to meet all organizations’ deep analysis needs.
  • Learn more about the winning entries in the slide show below:

      R es utilizado en el campo de la ciencia y de las finanzas. Dentro del campo de la ciencia lo podemos encontrar en Análisis de imágenes médicas, estadísticas generales,..., entre otras. Por el contrario, en finanzas, lo encontramos en econometría, análisis financieros, etc.
  • Create beautiful and unique data visualizations Representing complex data with charts and graphs is an essential part of the data analysis process, and R goes far beyond the traditional bar chart and line plot. Heavily influenced by thought leaders in data visualization like Bill Cleveland and Edward Tufte, R makes it easy to draw meaning from multidimensional data with multi-panel charts, 3-D surfaces and more. The custom charting capabilities of R are featured in many of the stunning infographics seen in the New York Times, The Economist, and the FlowingData blog.

  • Es conocida la existencia de una amplia variedad de paquetes estadísticos que se utilizan para el análisis de datos en la investigación clínica. Dentro de los más referenciados se destacan: STATISTICA, S-plus, SAS, SPSS, R y otros
  • Uno de los atractivos de R es que incluye un lenguaje de programación bien desarrollado, simple y efectivo, que admite condicionales, ciclos, funciones recursivas y posibilidad de entradas y salidas. Este lenguaje es orientado a objetos, muy parecido en su sintaxis a C/C++. Las facilidades de programación incluidas en R son muy amplias, lo que hace más eficiente la implementación de nuevos procedimientos, así como el uso reiterado de funciones existentes.
