plot.mids / Error in plot.new() : figure margins too large
...ge
I read the same question in thread from November 2005 (see below). I
actually have the same problem. Is it now possible to plot subsets of
mids.objects. If yes, how?
My datasets has 8 variables with missing values.
Thanks in advance,
Simon

Hi,
it is impossible to plot a subset of the variables at the moment, but we
could add it.
p.s. The latest version of mice is v1.14, which can be downloaded from
CRAN...

...random effects themselves. As far as I can see, this is
a straightforward use of MCMC to estimate model parameters; it is
not clear to me the results from the lmer() fit are used.

library MICE warning message
Hello.
I have run the command
imp<-mice(mydata, im=c("","pmm","logreg","logreg"),m=5)
for a variable with no missing data, a numeric one and two variables with binary data.
I got the following message:

standard error of variances and covariances of the random effects with LME
Hello,
how do I obtain standard errors of variances and covariances of the
random effects with LME comparable to those of for example MlWin? I know
you shouldn't use them because the distribution of the estimator isn't
symmetric blablabla, but I need a measure of the variance of those
estimates for pooling my multiple imputation results.
Regards,
Roel.

lmer / variance-covariance matrix random effects
Hello,
has someone written by chance a function to extract the
variance-covariance matrix from a lmer-object? I've noticed the VarCorr
function, but it gives unhandy output.

glmmpql and lmer keep failing
Hello,
I'm running a simulation study of a multilevel model with binary
response using the binomial probit link. It is a random intercept and
random slope model. GLMMPQL and lmer fail to converge on a
*significant* portion of the *generated* datasets, while MlWin gives
reasonable estimates on those datasets. This is unacceptable. Does
anyone has similar experiences?
Regards,
