Troubleshooting underidentification issues in structural equation modelling (SEM)
Hi all, hope someone can help me out with this.
Background Introduction
I have a data set consisting of data collected from a questionnaire that I
wish to validate. I have chosen to use confirmatory factor analysis to
analyse this data set.
Instrument
The instrument consists of 11 subscales. There is a total of 68 items in
the 11 subscales. Each item is scored on an integer scale between 1 to 4.

Confidence Intervals for Random Effect BLUP's
I want to compute confidence intervals for the random effect estimates
for each subject. From checking on postings, this is what I cobbled
together using Orthodont data.frame as an example. There was some
discussion of how to properly access lmer slots and bVar, but I'm not
sure I understood. Is the approach shown below correct?

Problem with pairs() in nlme
Dear r-helpers,
After successfully running
require(nlme)
vfr.lmL <- lmList(
estimate ~ (slant + respType + visField + hand)^2 | subject, vfr
)
pairs(vfr.lmL, id = 0.01, adj = -0.5) # Pinheiro & Bates (p. 141)
produces the following error:
Error in sprintf(gettext(fmt, domain = domain), ...) :
object "form" not found
Any guesses as to what I may have done wrong?

Here is my problem, i'm connecting to my share, which have a folder

plotting all subgroups with augPred
All,
I have a question RE plotting the prediction lines of a random effects
model via augPred. I'll illustrate via the Pixel dataset within the
nlme package:
library(nlme)
attach(Pixel)
fm1Pixel = lme(pixel ~ day + I(day^2), data = Pixel, random = list(Dog =
~ 1))
plot(augPred(fm1Pixel)) ### 10 fitted lines since there are 10 dogs
fm2Pixel = update(fm1Pixel, . ~ . + Side)

abline and plot(augPred) help
Dear all
as I did not get any response on my post about abline and
plot(augPred)) I try again. I hope I do not break some posting guide
rules. I would try to contact package maintainer directly but there
is stated to be R-core people, so I feel R-help list shall be OK.
I need to draw straight lines through augPred plotted panels
(vertical or horizontal) at specified point. I know I shall

augPred in lmer
I read the posts about augPred with lme, but does anyone know if there is a correlate for augPred for lmer? Specifically, I want to be able to use it to plot projections for all groups in an lmer class object using plot(augPred(lmer.object)).
Thanks,
Kyle

plot.augPred sorted and labelled according second factor
Hi
using this code example:
library(nlme)
fm1 <- lme(Orthodont, random = ~1)
plot(augPred(fm1))
is there any way to have the plots in each cell labelled and ordered
according to Orthodont$Sex? I.e. in addition to the bar with the label for
Orthodont$Subject there is another bar labelling the Sex of the subject?
thanks a lot

augPred with lme(...,subset=...)
Hello,
Is there a way to get augPred to work with lme if a subset statement is
used? For example, if I modify the example from ?augPred.lme to include
a subset statement, I get the following error:
fm1 <- lme(Orthodont, random = ~1, subset=distance>19)
augPred(fm1, length.out = 2, level = c(0,1))
Error in tapply(object[[nm]], groups, FUN[["numeric"]], ...) :

Fix for augPred/gsummary problem (nlme library)
Dear R-users,
I am a newbie to this site and a relative new-comer to S/R, so please tread lightly, for you tread...
There have been several posting relating to problems with augPred() from the nlme library. Here is a "fix" for one of these problems which may lie at the root of others.
In my case the problem with augPred() lay in gsummary(), which augPred() uses, causing it to fail.

How do I overlay two trellis plots of lme fitted lines produced by plot.augPred?
Hello,
I want to use lme to fit two (or more) models, and then compare the fits
on each individual. I know how to write my own code to do this (for each
individual, plot the raw data, followed by lines() to plot each fitted
curve) but I would like to use plot(augPred(... as it produces a nice
trellis plot. I thought I could do this with par(new=T) but it does not
seem to work.

Observed responses in 'augPred' data frame - Wrong order ?
Dea-R community.
I'd like to draw your attention to an issue I have recently
encountered while doing my current data analysis.
I've got an unexpected (to me) result from the command:
> augPred(lmList(my.object)),
'my.object' being a grouped data frame of class:
> class(my.object)
[1] "nfnGroupedData" "nfGroupedData" "groupedData"

augPred plot in nlme library
All,
I'm trying to create an augPred plot in the nlme library, similar to the
plot on
p.43 of Pinheiro & Bates (Mixed Effects Models in S and S-Plus) for
their Pixel data.
My data structure is the same as the example but I still get the error
msg below.

panel ordering in nlme and augPred plots
Dear all
I am trying nlme together with Pinheiro/Bates book. I constructed
grouped data object with suitable plotting layout (according to
some common factor, panels from bottom to top are in increasing
order).
When I do nlme(... some stuff...) I get fitted object which I can plot
with
plot(augPred(fit.nlme6, level=0:1))
but it results in completely different ordering. Is there any way

I encountered strange behaviour of augPred with virtually the same data
First I made groupedData object.

strange nlme augpred behaviour
Hi
Well, yes I tried it about two weeks ago but my post did not get through as it still awaits moderator approval. I could check which column is offending but actually it is only minor nuisance, I can live with selection of columns before fitting a model. What seems to me strange is that both full dataset and only selected colums gave me identical fit results but only one works within augPred.
