Why do I get different results for type III anova using the drop1 or Anova command?
Dear experts,
I just noticed that I get different results conducting type III anova
using drop1 or the Anova command from the car package. I suppose I made
a mistake and hope you can offer me some help. I have no idea where I
got wrong and would be very grateful for explaination as R is new
terrain for me.
If I run the commands in line, they produce the same results. But if I
run them in

Syntax of Levene's test
Dear All
I am trying to use Levene's test (of package car), but I do not
understand quite well how to use it. '?levene.test' does not
unfortunately provide any example. My data are in a data frame and
correspond to 4 factors plus response. Could someone please give me an
example about how to use the command
levene.test(y, group)
?
Thanks in advance,
Paul

Musings on the TableGen -emit-dag-isel backend
A rather notorious aspect of TableGen is the time required to run the
-emit-dag-isel backend on some targets, including AMDGPU and X86. I added a
timing feature to TableGen and timed the AMDGPU run.

Musings on the TableGen -emit-dag-isel backend
I wouldn't want to be too hasty about simply removing the relaxation
algorithm. The size and speed of the compiler affects all users, but the
time to compile the compiler "only" affects us compiler developers. And I
speak as a developer who is heavily affected by the time to compile the
AMDGPU backend.
One off-the-cuff idea (I haven't even looked at the code yet): could we

This is great! Thanks Paul!
I think that the 9x reduction in compile-time is well worth the 4% size increase. TableGen's run-time has been a sore point and a source of complaints for quite some time.

This is the size of the table, not the size of the overall binary, right? I would imagine that a 4% growth in the size of the table is a substantially smaller growth in the total executable size of, say, clang. If the overall growth is minuscule (say, under 1%), then this seems like the clear path forward.
I’m also optimistic that we might be able to find other ways to shrink the tables to make

Compile time from IR
Hi,
I have a compiler project using an LLVM backend (compiled for 64 bit windows), and since it has started to get to production level source code sizes the compile times have gotten somewhat extreme (around 30 mins each time).
Not sure what is the best metric for measuring whether 30 mins is reasonable. The .ll output file is ~1.5 million lines.
A snip of the top of the stats output is
