...l. I'd like to generate a sample of n observations from a k dimensional multivariate normal distribution with a random correlation matrix. My solution: The lower (or upper) triangle of the correlation matrix has n.tri=(d/2)(d+1)-d entries. Take a uniform sample of n.tri possible correlations (runi(n.tr,-.99,.99) Populate a triangle of the matrix with the sampled correlations Mirror the triangle to populate the other triangle forming a symmetric matrix, cormat Sample n observations from a multivariate normal distribution with mean vector=0 and varcov=cormat Problem: This approach violates t...

I want to generate 1,000 random samples of sample size=1,000 from ZINB. I know there is a rnegbin() to generate random samples from NB, and I know I can use the following process: do i=1 to 1000 n=0 do i=1 to 1000 if runi(1)>0.1 then x(i) = 0; else x(i)=rnegbin(); n=n+1; if n>1000 then stop; end; output; end; Anybody can help me out with the R code? Thanks very much ahead of time. Heyen

Hi, I was learning rails and have completed some projects. On my laptop everything worked for quite some time. However now when I run rails new testapp, for example it doesn''t generate even the first testapp. How can I completely reinstall a rails environment on my mac? I ran several step by step tutorials how to do this, but it seems that the old rails environment is conflicting. I

I have a problem with running Rails 0.13.1 with scgi_rails 0.4.3 and Apache. After running for some time (more than a day), the SCGI process stops with the following error (from scgi.log): -- [ERR][24189] Collecting thread: Too many open files [ERR][24189] /usr/local/lib/ruby/gems/1.8/gems/scgi_rails-0.4.3/lib/scgi.rb:188:in `accept''

Hi all, I''ve a problem when submitting a form : the URL seems to be invalid. I really don''t see the way I should try to solve that problem. I searched on the web, but didn''t found any kind of that problem. Here is the code : require ''mechanize'' agent = WWW::Mechanize.new page =

I have searched for this problem and found this link that says this problem was fixed (for WoW) in Wine 0.9.32 : http://bugs.winehq.org/show_bug.cgi?id=6323 Is anyone else having problems with the numeric keypad not showing numbers under Wine 1.0 ? I have everything working for putty except this crippling problem. I don't feel I can offer a terminal emulator solution where you cannot use

Hey hope this opne is a "make senser". Has anyone tried the "Subject line" combo?, I''ve compiled a dozen src.rpm kernel 3.0 and 3.1 packages with no luck to try native upstream Dom0 kernel support with no success, just a kernel oops and constant reboots. I followed Fedora''s wiki on building a custom kernel, even used F16''s .config which also was a
