In Julian Faraway's text on pgs 117-119, he gives a very nice, pretty simple description of how a glm can be thought of as linear model with non constant variance. I just didn't understand one of his statements on the top of 118. To quote : "We can use a similar idea to fit a GLM. Roughly speaking, we want to regress g(y) on X with weights inversely proportional to var(g(y).

Dear R Users, Given two vectors, say a = seq(2) and b = seq(3), I want to make an 2*3 array, where (i,j) element is list(a=a[i], b=b[j]). I tried the outer() function but it generates an error message that I don't understand, see below. What do I do wrong? The expan.grid function is not good enough since I need a solution that works when a and b are not atomic, say a=list(list(x=1,

Hi, I''m running into something weird here. I''m using RH5.1 with tcp_wrappers 7.6. The syntax for hosts.allow and hosts.deny is: <service list> : <access list> [ : <shell_command> ] Everything works when I _don''t_ use the shell_command. I used the _exact_ line as in the man-pages utilising "safe_finger" (comes with tcp_wrappers), tcpdchk

Hi, Using ferret and acts_as_ferret. Great work. Is there a way to define some synonyms (searchable words that would not appear in the texts ? Like stop words, but instead of being removed from query and index, they would be added ;-) Can some synonyms be regexp ? I''d like for instance to have ? (oelig) be equivalent to oe in French. Or maybe an utf8 normalization could achieve

Hello All, I could use a recommendation if anyone has a moment. I have the T100P but I have not gotten my service yet. I want to have at least 12 lines of digital voice with DID. Should I just seek out a PRI ISDN provider or is there something else I should look for? I want to keep cost as low as possible. Also, I want to own my own router for the phones since it is always a hassle to get

Hi Are there any known security holes or necessary precautions in using port forwarding with ipportfw? I'm planning on forwarding ports from an outer firewall/router (connected to the Internet) to a host in the DMZ, then on from the DMZ host to the inner firewall, and finally from the inner firewall to some host on the inside.
