...n. The problem is that I have unbalanced classes e.g. the first one is much bigger than the second one and therfore the svm is biased to the first class. If I manually adjust the class size the bias disappears. The question is then how to include this unequal class distribution to the svm (e.g. via wheights or costs)? Yours, Frank -- Frank G.

Hello R users, I have numerical data sampled on two grids, each one shifted by 0.5 from the other. For example: grid1 = expand.grid(x=0:3, y=0.5:2.5) grid2 = expand.grid(x=0.5:2.5, y=0:3) gridFinal = expand.grid(x=0.5:2.5, y=0.5:2.5) plot(gridFinal, xlim=c(0,3), ylim=c(0,3), col="black", pch=19) points(grid1, xlim=c(0,3), ylim=c(0,3), col="red", pch=19) points(grid2,

...resences, and the total area is about 550.000 square km. So we have a real problem, when we perform a GAM, if we consider only the same amount of absences than presences. We have thought to use a greater number of absences but in this case we shoud downweight them. Does anybody know how to use the ?wheight? term? thank you in advance daniel -------------------------------------------------------------------------- Mensaje enviado mediante una herramienta Webmail integrada en *El Rincon*: ------------->>>>>>>> https://rincon.uam.es <<<<<<<<-----...

I run samba for a small business domain (less than 10 users), which to me, seems like a common (and good) use case. When I ran a Windows server, it did it all. AD DC and file server. I have figured out how to get samba to do the same, but not without many a headache and some I'm sure, unsupported workarounds. While I fully understand the reasoning behind the desire to run separate servers

Hi all, I'm using 'show translation' to help dimension my system, but I confused by the results I get. My 2 test systems (results below): an AthlonXP 2000+ (1.3GHz) and a Pentium D930 (duo-core, 3.0GHz) produced similar results (D930 is slightly faster). Googling shows that others have similar results running on other CPU speeds >2.0GHz. At first glance, it would look like the

...: School of Life Sciences study: Ecological and Environmental studies ----------------------------------------- I have been using R for teaching survival analysis and analysis of categorical data (glm) for 2 years at the Autonomous University of Barcelona, Spain. Reasons: 1. R is free and low wheight. Students can have their own copy. 2. We have campus license of SPSS but this does not have easy capabilities for glm nor parametric survivam models. -- Victor Moreno V.Moreno at ico.scs.es Servei d'Epidemiologia i Registre del Cancer http://lbe....
