I've posted a sample file for estimating loglinear models for square tables (mobility models) at http://www.xs4all.nl/~jhckx/mcl/R/ Comments and suggestions are welcome. John Hendrickx

Hi- Is anyone working on multiple comparisons of means or post-hoc tests (ie: Tukey, Bonferroni) for R? I saw in the winter 98' archives of the R mailing lists that these tests had not been implemented yet, I was just wondering if I could look foward to having them. ;-) I also looked through the contributed packages and didn't see anything that offered such tests. I guess I could check

...first and then ocfs2_inode_lock. But if ocfs2_inode_lock failed, it goes to out_sems without unlocking rw lock. This will cause a bug in ocfs2_lock_res_free when testing res->l_ex_holders, which is increased in __ocfs2_cluster_lock and decreased in __ocfs2_cluster_unlock.

...ntial candidate topic. Since we are all new to LLVM we would like to ask for experts' opinions here if there already is a well known implementation of loop fusion pass existed, and if not, is there a particular reason that it is not done given such optimization is fairly standard?

Matt, Here's a Bonferroni-corrected multiple one-sample t-test that I wrote some years ago. It took a while to get it into R, as na.omit doesn't seem to handle vectors and I had to write a quick kludge (na.remove). Another more general point was that I discovered that the help page for t.test gives the name "parameters" for the degrees of freedom, as in S. However, the name

I know that the validation works on the insured object alone if I create one and attempt to save it with invalid data. Why does qi.save! return true below? It''s like it didn''t try to save the insured object. In script/console I see: >> ins = Insured.new => #<Insured:0x37345e0 @new_record=true, @attributes={"city"=>"", "address1"=>"" , "name&q...

Hi Qi, No, we don’t have loop fusion. The loop fusion transformation itself is easy, but the profitability and legality checks are challenging. For legality, you would need to analyze the memory that you access and figure out that it is legal to fuse the loops. For profitability you would need to pre...

...e.com> Subject: ocfs2: fix use-after-free when unmounting read-only filesystem Date: Mon, 22 May 2023 11:21:12 +0100 It's trivial to trigger a use-after-free bug in the ocfs2 quotas code using fstest generic/452. After mounting a filesystem as read-only, quotas are suspended and ocfs2_mem_dqinfo is freed through ->ocfs2_local_free_info(). When unmounting the filesystem, an UAF access to the oinfo will eventually cause a crash.
