Little's Chi Square test for MCAR?
Hi. Can anyone point me to any module in R which implements "Little's Chi Square test" for MCAR. The problem is that i have around 60 behavioural variables on a 6 point categorical scale which i need to test for MCAR and MAR. What i can make out from preliminary analysis is that moderate (0.30 to 0.60) correlations may be present in several variable pairs leading me to suspect

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) x1 <-

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.   R code:   x <-

porting numbers in UK telewest/bt/adept
A client used to use BT isdn30 and ported the numbers to telewest several years ago. Now, the client moved to adept telecom. I *think* adept resells BT products. We got new numbers from adept (bt?) and the old pbx on the telewest lines forwards the calls to the new numbers. On the adept line I got a digium card in an opteron supermicro server. ztcfg gives me over 99.99 pretty much all the time.

Package of EM and MI for IRT in R
Dear all members, I am Phd. candidate student at Chulalongkorn U., Thailand. I am interested in expectation maximization algorithm (EM) and multiple imputation (MI) for imputation missing values(missing at random(MAR) and missing not at random (MNAR)) in IRT (3-PL). So, I want to know about package in R or function of EM and MI for simulate this problem I am looking forward your answer.

[R-pkgs] New package "list" for analyzing list survey experiments
I know nothing about your package, but "list" is a terrible name for it, as "list" is also the name of a data type in R. -- Jeff

Wine 0.9.55 late for (k)ubuntu?
Hi all, I noticed on the web site that Wine 0.9.55 has been released on February, 8th, but still I don't see the update on Adept Manager. I'm using Kubuntu 7.10 64 Bits and I added the Wine's official repository on the Adept repository list. Is it just me or there is a problem on the Wine repository? Thank in advance. -- Marco Di Fresco

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

stable + squid 2.5_3
I seem to be having a problem, but I'm not sure if it's -stable, Squid, or neither. I've been running -stable+Squid on a Dell 4600 for a couple years now. All has been well, but after upgrading to Squid 2.5_3 (which was also done on a couple other, less-loaded, -stable machines without this issue to date), I occasionally get errors in my cache.log and this AM Squid died and required

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

Rsync ssh script execution fails under cron?
I've spent more than a day trying to write a script to backup my remote server to a local machine using ssh. The script works perfectly when I execute it directly (and I've gotten a number of variations to work okay), but I can't get cron to successfully execute it. There is no result output, so it seems cron is hanging on something, but I don't know what. I'm running it as

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)

Date problem after import
Hi, am running into an import problem: After I upgraded an Mac OS X 10.5.8 Server to Mac OS X 10.6, not all, but quite some mails show wrong dates. They are dated to the year 2020, which is obviously not possible for mail that has been sent long ago. Now 10.5 to 10.6 is a move from cyrus to dovecot and the migration scripts used by Apple are supposed to do a nice migration. I have seen this
