* Many people are not yet subscribed to the statslausanne mailing-list; please forward appropriately to your colleagues * Our next statistics forum for people interested in quantitative methods in biology and medicine will take place this Thursday 24 May at 11h00 in the reading room (2020) of the Genopode building (2nd floor, same level as the main entrance) in Dorigny. The speakers will be Darlene Goldstein and Alix Leboucq from EPFL, who will talk about Combining microarray studies with missing information Abstract: Meta-analysis of microarray studies to produce an overall gene list is relatively straightforward when complete data are available. When some studies are missing information (for example, some studies have only a ranked list of genes instead of complete primary data), a common approach is to reduce all studies to ranked lists prior to combining. Since this step entails a loss of information, we wondered whether we could improve the final list by attempting to preserve the information available for each study. We therefore consider a modeling approach to combine the studies using the type of information available in each study: full data matrix, summary statistics, or ranks for each gene. We will discuss progress in the development of the model and some preliminary results from a simulation study of model performance.

* Many people are not yet subscribed to the statslausanne mailing-list; please forward appropriately to your colleagues * * NOTE: for those of you who came to this meeting previously, the location has changed * Our next statistics forum for people interested in quantitative methods in biology and medicine will take place this Thursday, 10 May at 11h00 at the IUMSP, Biopôle 2, route de la Corniche 10, in the conference room (1st floor). The speaker will be Alfio Marazzi, from the IUMSP, who will talk about "The analysis of hospital cost and length of stays: robust estimation of the generalized loggamma model." Abstract: In the first non-technical part of my talk, I will motivate the use of robust statistics in the analysis of hospital length and cost of stay. Several methods for robust regression with asymmetric errors have been developed for this purpose. In the second technical part of the talk, I will briefly present a recently developed robust method to estimate the generalized loggamma model (a very flexible family of bsymmetric and asymmetric distributions, including normal, log-Weibull, and log-gamma).
