similar to: Error in Lordif: slope is missing or negative

Hi All, ? I am trying to use the lordif package in R and can't figure out the reason for the above error when I try to run the calctheta() function. ################## # read data using foreign package - must be Stata 11 or earlier racedata<- read.dta("race.dta")??? # item responses resp.data<-racedata[,-c(1:2)] # grouping variable is in the second column

Dear R-List, I tried to fit a partial credit model using the "pcmdat" from eRm-package comparing the results of mirt, eRm, ltm and winsteps. The results where quite different, though. I cannot figure out what went wrong and I do not know which result I can rely on. This is what I did in R library(mirt) #load(file="u3.RData")

Dear useRs, does any of you have suggestions on how to conduct a proper DIF analysis starting from a model of class gpcm (from the wonderful package ltm by prof. Rizopoulos)? difR will handle only dichotomous items, and I have a mix of dicho- and polytomous ones (that's why I chose the partial credit model). I also found the package lordif, but I'm not really sure if that's what I

Hello list :) I am having issues setting the "read-only" flag via Windows Explorer on my AIX Samba share and I was hoping someone out there would be able to point me into the right direction to solving this issue... I have on my AIX 7.1 system installed Samba 3.6.24 and configured, joined to our Windows domain successfully. The samba binaries I got from perzl.org/aix In my smb.conf I

Hai, Can you tell the following that helps. OS ? Samba Version? ( pre-builded or source ) Kernel version? I think you need to wait for 4.9.4 if all patches ive seen on vfs_fruit are getting in. These might help. Go through bugzilla, you might find more about this here. Greetz, Louis > -----Oorspronkelijk bericht----- > Van: samba [mailto:samba-bounces at lists.samba.org]

I am really new to R and ran across a need to take a data matrix and calculate an approximation of the first derivative of the data. I am more than happy to do an "Excel" kind of calculation (deltaY/deltaX) for each pair of rows down the matrix, but I don't know how to get R to do that kind of calculation. I'd like to store it as a 3rd column in the matrix as well. My data

Hi all, I am trying to run a glm with mixed effects. My response variable is number of seedlings emerging; my fixed effects are the tree species and distance from the tree (in two classes - near and far).; my random effect is the individual tree itself (here called Plot). The command I've used is: mod <- glmer(number ~ Species + distance + offset(area) + (1|Plot), family = poisson)

Listing directories with many files (10000+) from a Windows client is nociceably slower when vfs_fruit is enabled on the samba server compared to the same setup without vfs_fruit. On my setup it's roughly 2.5 times slower. To me it looks like this is caused by the getxattr call which is only present with vfs_fruit activated and introduces an additional delay of ~ 0.00033 s per listed

After much effort I upgraded our fairly large Rails app from 2.1 to 2.3. After deployment yesterday I noticed an across the board increase in response times. It seems that every call to memcache now takes 10x longer than before. Here are some example numbers from my development log (below), with memcache running locally. We see similar scale of performance drop in production as well - average

Hi Steven- Nice, but will this not break Windows? From an initial glance over your patch, it seems to assume the existence of mmap() in some form or other.
