One of the decisions to be taken when performing a systematic review is whether to choose a random or fixed effects model. Very briefly, a fixed effects model is chosen if the studies in the metaanalisys are homogeneous, and random effects model is preferred otherwise. This video illustrates the question:

Una de las decisiones que hay que tomar cuando se lleva a cabo una revisión sistemática es si se debe escoger un modelo de efectos fijos o de efectos aleatorios. De manera muy resumida, se escogen efectos fijos si los estudios incluidos en el metaanálisis son homogéneos, y efectos aleatorios en caso contrario. Este vídeo ilustra la cuestión.

Evidence Based Healthcare and Biostatistics for those who, as many doctors and health workers, hate numbers (thus the name of the blog). It aims to be a way to share ideas, resources, tools and training links, and a place to discuss specific health issues from an epidemiological perspective. Our desktop is a portrait of Karl Pearson (1857 - 1936), a prominent figure in Statistics and author of the book "The Grammar of Science" Please Share your comments!

More on Bayesian inference and the Bayes Theorem/ Más sobre Inferencia Bayesiana y el teorema de Bayes
Sharon Bertsch McGrayne makes a lovely presentation (click here) on Reverend Thomas Bayes and his theorem at the The Singularity Summit held in New York in 2011.
Allen Downey features a lesson on Bayesian Inference made as simple as possible. This is his blog.
The MIT offers a class on Bayesian inference here. The second part is offered here.
This is the article on Bayes´ Theorem at the Stanford Enciclopaedia of Philosophy

GAPMINDER
GAPMINDER is a beautiful tool for statistical data display, created by Ola Rosling, Anna Rosling Rönnlund and Hans Rosling. The latter is a professor at the Karolinska Instutet, and we have had some very interesting presentations by him in previous threads of the blog.
----------------------------------------------------------------------------------------------------
GAPMINDERes una bella herramienta para la representación de datos estadísticos, creada por Ola Rosling, Anna Rosling Rönnlund y Hans Rosling.
Este último es porfesor del Karolinska Instutet y ya hemos visto algún vídeo muy interesante realizado por él en entradas previas del blog.
