Unbalanced ANOVA in R?
Hi all
I'm trying to complete a textbook example originally designed for SPSS
in R, and I therefore need to find out how to compute an unbalanced
ANOVA in R.
I did a search on the mailinglist archives an found a post by Prof.
Ripley saying one should use the lme function for (among other things)
unbalanced ANOVAs, but I have not been able to use this object.
My code gives me an error.. Why

HOWTO Stratum 1 NTP server under CentOS 7
Hello everyone,
If anyone is interested, I have created a HOWTO
on running a Motorola GPS receiver connected to
a CentOS 7 box via serial port (com1),
with 1PPS over DCD.
The trick here is that CentOS 7 uses systemd
and setup was a bit different. Anyway,
everything works.
The result is a highly accurate NTP server, Stratum 1.
Here is the documentation.

The right thing to do next is to ask for this change upstream, so people can get regular updates and stay secure.

Perhaps both the 'chrony' and 'ntp' packages should Provide
'server(smtp)' (similar to how sendmail/postfix work with SMTP)? That
way anaconda could just require 'server(ntp)'.
Either way, this isn't something

ntpd stuck on stratum 16 = not synced
Maybe there's an ntp expert out there who can help me with this. I have an NTP server serving our local network. It is
set up to use pool.ntp.org servers for it's upstream sync. ntpq -p reveals that the server is stuck on stratum 16,
which I understand means "not synced". The clients are unable to sync with my local server because of this. Here's the
output of ntpq -p

HOWTO Stratum 1 NTP server under CentOS 7
Alexander,
First off, CentOS7 came with cronyd. Which was very annoying
because when I tried to remove it, it had 2 prereqs:
anaconda
initial-setup
Now, I don't know why the setup program kept these
2 around. I think CentOS7 needs a bit growing up.
Anyway, I disabled chrony:
systemctl disable time-sync
systemctl stop time-sync
Then I installed ntp. However, when I started it

Anova with repeated measures for unbalanced design
Dear all,
I need an help because I am really not able to find over internet a good example
in R to analyze an unbalanced table with Anova with repeated measures.
For unbalanced table I mean that the questions are not answered all by the same
number of subjects.
For a balanced case I would use the command
aov1 = aov(response ~ stimulus*condition + Error(subject/(stimulus*condition)),
data=scrd)

unbalanced anova with subsampling (Type III SS)
Hello R-users,
I am trying to obtain Type III SS for an ANOVA with subsampling. My design
is slightly unbalanced with either 3 or 4 subsamples per replicate.
The basic aov model would be:
fit <- aov(y~x+Error(subsample))
But this gives Type I SS and not Type III.
But, using the drop() option:
drop1(fit, test="F")
I get an error message:

Two-way Random Effects with unbalanced data
Hi there,
I am looking to fit a two-way random effects model to an *unblalanced*
layout,
y_ijk = mu + a_i + b_j + eps_ijk,
i=1,...,R, j=1,...,C, k=1,...,K_ij.
I am interested first of all in estimates for the variance components,
sigsq_a, sigsq_b and sigsq_error.
In the balanced case, there are simple (MM, MLE) estimates for these; In the
unbalanced setup,

logistic regression: wls and unbalanced samples
Greetings from Rio de Janeiro, Brazil.
I am looking for advice / references on binary logistic regression
with weighted least squares (using lrm & weights), on the following
context:
1) unbalanced sample (n0=10000, n1=700);
2) sampling weights used to rebalance the sample (w0=1, w1=14.29); e
3) after modelling, adjust the intercept in order to reflect the

anova in unbalanced data
Hi all,
Say I have the following data:
a<-data.frame(col1=c(rep("a",5),rep("b",7)),col2=runif(12))
a_aov<-aov(a$col2~a$col1)
summary(aov)
Note that there are 5 observations for a and 7 for b, thus is
unbalanced. What would be the correct way of doing anova for this set?
Thanks,

Unbalanced Design Power Analysis
I have an unbalanced design I would like to run a power analysis on.
What I have been able to find has pointed me to using the pwr.f2.test
function as described below. My problem is that I don't know how to
appropriately define the numerator and demoninator df.
If someone can help here is some more info about my design.

panel regression with twoways random effects, on unbalanced data?
Dear R users
What would be the best way to approach estimating a panel regression
with twoways random effects, on unbalanced data? Unfortunately, the
"plm" package has no implementation of twoways random effects for
unbalanced data. Currently I'm considering two approaches:
- extend "plm" to cover this type of panel regression. (For the
authors, cc'ed:) Would

rpart unbalanced data
Hello all,
I am currently working with rpart to classify vegetation types by spectral
characteristics, and am comming up with poor classifications based on the fact
that I have some vegetation types that have only 15 observations, while others
have over 100. I have attempted to supply prior weights to the dataset, though
this does not improve the classification greatly. Could anyone supply some
