Registers for i128 data type not registered in X86
Hi,
I have a set of new registers for x86 which I defined in
X86RegisterInfo.td to be:
def POI0: X86Reg<"poi0", 0>;
def POI1: X86Reg<"poi1", 1>;
def POI2: X86Reg<"poi2", 2>;
def POI3: X86Reg<"poi3", 3>;
def POI4: X86Reg<"poi4", 4>;
def POI5: X86Reg<"poi5", 5>;
def POI6: X86Reg<"poi6",

Additional instructions created
Hi all,
I've got a few new registers and I've extended the pointer size to be 128
bits. For allocas, that is done by adding another SelectionDAG after
FrameIndex that extends it to 128 bits. That seems to work okay, except
that the final representation throws in additional instructions. For
example for a piece of code such as:
int a;
int* pointer = &a;
it returns

taking rows from data.frames in list to form new data.frame?
Hi,
I am having a problem figuring out how to extract a subset of rows. I
have a list with 68 similar data.frames. Each data.frame is 500 rows
by 5 columns. I want to take one row from each data.frame based upon
the data in a particular column (i.e. it matches a symbol). For
example:

interpreting "not defined because of singularities" in lm
I run lm to fit an OLS model where one of the covariates is a factor with 30 levels. I use contr.treatment() to set the base level of the factor, so when I run lm() no coefficients are estimated for that level. But in addition (and regardless of which level I choose to be the base), lm also gives a vector of NA coefficients for another level of my factor.
The output says that these coefficients

how to deal with singularities in lm()

I got the report
Coefficients: (1 not defined because of singularities)
while trying to get my model's coefficients from lm()
What shall I do to avoid it and get the one missing coefficient?
Thank you.

Package survey: singularities in linear regression models
Hello,
I want to specify a linear regression model in which the metric outcome
is predicted by two factors and their interaction. glm() computes
effects for each factor level and the levels of the interaction. In the
case of singularities glm() displays "NA" for the corresponding
coefficients. However, svyglm() aborts with an error message. Is there a
possibility that svyglm()

GLM and LM singularities
Hi-
I'm wrestling with some of my data apparently not being called into a GLM or
an LM. I'm looking at factors affecting fish annual catch rates (ie. CPUE)
over 30 years. Two of the factors I'm using are sea surface temperature and
sea surface temperature anomaly. A small sample of my data is below:

Summary coefficients give NA values because of singularities
Hello,
I have a data set which I am using to find a model with the most significant
parameters included and most importantly, the p-values. The full model is
of the form:
sad[,1]~b_1 sad[,2]+b_2 sad[,3]+b_3 sad[,4]+b_4 sad[,5]+b_5 sad[,6]+b_6
sad[,7]+b_7 sad[,8]+b_8 sad[,9]+b_9 sad[,10],
where the 9 variables on the right hand side are all indicator variables.

Nested model - "singularities not defined"
I am using a nested model in R and the lm output shows 47 not defined
because of singularities and I have no idea why. Any help on why this is
happening or how to fix this problem would be very much appreciated. Below
is the output I received from R.
Thanks and happy holidays!

Hello,
I am trying to run a linear regression analysis on my data set. For some

My linear regression looks this way (I am using only partial data, which
is selected by flags):

log(1/features.meanOver.frust[flags]) +

I'm using Nouveau in ubuntu bionic. My problem is, when I connect a
second Monitor to my Laptop on DVI-D connector, the monitor is not

So in Fedora rawhide we are now building llvm 3.7.1 into the lots of

However I'm running into a major problem with the fact that sometimes

of the process.

Model file from ranking using Xapian::Letor
Hello,
I have attached a model file which can be used to rank new queries.
Disclaimer: I don't remember if its is the updated one or the one with
which I evaluated the API before. But it should work with your new queries
with libsvm based letor module.
