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

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.

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.
sincerely yours,

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:
