search for: fundment

This is so frustrating. Is RoR that easy to learn or is it hype or is it just me? I wonder how many newbies like me are surfing the docs trying to get a clue of the basics. Every tutorial I find is much the same, and seems to skip the fundmental parts. How should you understand the Ruby API http://api.rubyonrails.org/? What is < ActionController::Base? Can''t I set a cookie under that? Or do I have to use that under ActionController::Cookies? I don''t get it. -- Posted via http://www.ruby-forum.com/.

...1 (as I think it should be to use the transformed variable meaningfully) but much lower. With higher added values (and a right skewed variable) the lambda estimate was even negative and the correlation between the transformed variable and the original varible was -.91!!? I guess that is something fundmental missing in my current thinking about box-cox... Best, Holger P.S. Here is what i did: # Creating of a skewed variable X (mixture of two normals) x1 = rnorm(120,0,.5) x2 = rnorm(40,2.5,2) X = c(x1,x2) # Adding a small constant Xnew1 = X +abs(min(X))+ .1 box.cox.powers(Xnew1) Xtrans1 = Xnew1^....

As far as I understand the figures above correspond to vhost-iommu against vsmmuv3. In the 2 cases the guest owns stage1 tables so the difference comes from the I...
