Little's Chi Square test for MCAR?
Is there any further development in R to identify the missing data Mechanism?
Would you please help ?

New to R
I'm relatively new to R, and not particularly adept yet, but I was wondering
if there was a simply way to simulate missing data that are MAR, MNAR and
MCAR. I've got a good work-around for the MCAR data, but it's sort of hard
to work with.

Little's MCAR test
L.S.,
Does anyone know if there is an R library which implements Little's MCAR
test for completely at random missing values? It is implemented in SPSS and
SAS, and widely mentioned in the literature.
Thanks in advance!

Create DataSet with MCAR type
Dear all
I want to create dataset with MCAR type from my dataset.
I have my dataset with 100 records, and I want to create dataset from this
dataset to missing 5 records.
How I can do it.

R-help question
Hi there,
I have subscribed to R-help but am not sure how to view or post questions? I think this is the right way.
I am planning on doing a multivariate regression investigating the relationship between depression (a continuous variable) and social support variables (mostly continuous, some categorical) among older people. I have a number of demographic and health-related variables that I am

multiple imputation manually
Hi,
I want to impute the missing values in my data set multiple times, and then
combine the results (like multiple imputation, but manually) to get a mean
of the parameter(s) from the multiple imputations. Does anyone know how to
do this?
I have the following script:
y1 <- rnorm(20,0,3)
y2 <- rnorm(20,3,3)
y3 <- rnorm(20,3,3)
y4 <- rnorm(20,6,3)
y <- c(y1,y2,y3,y4)

Not missing at random
Hello!
I would like to sample 30 % of cases (with at least 1 value lower than 3) and
among them I want to set all values lower than 3 (within selected cases) as NA
(NMAR- Not missing at random). I managed to sample cases, but I don’t know how
to set values (lower than 3) as NA.

Quasipoisson with geeglm
Dear all,
I am trying to use the GEE methodology to fit a trend for the number of butterflies observed at several sites. In total, there are 66 sites, and 19 years for which observations might be available. However, only 326 observations are available (instead of 1254). For the time being, I ignore the large number of missing values, and the fact that GEE is only valid under MCAR. When I run the

Covariance of data with missing values.
I have a data matrix X (n x k, say) each row of which constitutes an
observation of
a k-dimensional random variable which I am willing, if not happy, to
assume to be
Gaussian, with mean ``mu'' and covariance matrix ``Sigma''. Distinct
rows of X may
be assumed to correspond to independent realizations of this random
variable.
Most rows of X (all but 240 out of 6000+ rows)

Libvirt uses XML for most of the APIs. Depends what you need to do you can
transform it with xmltodict or use some higher level API. I'm not sure I can

GetPrinter Level 2 does not get devmode
Hi all,
I have uploaded the printer drivers succesfully on RedHat Linux/ Samba
2.2.4 server. I can download and print without any problems. But when I do
Windows API call GetPrinter with PRINTER_INFO_2, the devmode in
printer_info is always null. My code looks like

diff in a dataframe
I have a dataframe say:
date price_g price_s
0.34 0.56
0.36 0.76

and so on. say, 1000 rows.
Is it possible to add two columns to this dataframe, by computing say
diff(log(price_g) and diff(log(price_s)) ?
The elements in the first row of these columns cannot be computed, but

how to play multiple speex audio streams simultaneously
Hello,
In a way similar to speexclient voip example, I want to have a voip
application where 3 or more users can interact. This creates the following
problems "1. How to playback 2 or more audio streams such that they appear
overlayed (parallel)". The audio streams are speex encoded.
I have few approaches in mind.

Help with integrating R and c/c++
Hi,
I have been using R for close to two years now and have grown quite
comfortable with the language. I am presently trying to implement an
optimization routine in R (Newton Rhapson). I have some R functions that
calculate the gradient and hessian (pre requisite matrices) fairly
efficiently. Now, I have to call this function iteratively until some
convergance criterion is reached. I think the

[LLVMdev] GSoC:Loop Reversal Transformation
Hi Matt, All,
Thanks for looking into this and your suggestions.
I compiled the program with -O3 optimization level (clang -O3) on X86_64
target.
After your suggestion, i ran the program with iteration of 10000 runs and
found that average runtimes are (attaching data collected as well)
Forward loop traverse : 2.006 milli seconds
Reverse loop traverse : 1.531 milli seconds
Yes, i agree that
