Using mixed models to analyze Longitudinal intervention
Dear R List,
I am trying to use mixed models to analyze an intervention and want to make
sure I am doing it correctly. The intervention is for lowing cholesterol
and there are two groups: one with an intervention and one without. The
subjects were evaluated a differing amount of time, so there were between 2
and 7 visits, equally spaced.
Sample output is below. TC...

interrupted time series analysis using ARIMA models
Hi R-users,
I am using arima to fit a time series. Now I would like to include an intervention component "It (0 before intervention, 1 after)" using different types of impacts, that is, not only trying the simple abrupt permanent impact (yt = w It ) with the xreg option but also trying with a gradual permanent impact (yt= d * yt-1 + w * It ), following the filosophy of Box and Tiao...

Lattice xyplots plots with multiple lines per cell
Hello,
I need to plot the means of some outcome for two groups (control vs
intervention) over time (discrete) on the same plot, for various subsets
such as gender and grade level. What I have been doing is creating all
possible subsets first, using the aggregate function to create the means
over time, then plotting the means over time (as a simple line plot with
both control & in...

nested cross-sectional design using lmer or nlme
Dear all, I'd appreciate some advice on the following problem. I'm
attempting to analyse a nested cross-sectional design in which an
intervention was offered to a series of randomly selected (small)
communities, so the unit of randomisation is the community. All
available individuals in each community were interviewed before the
intervention and again at follow-up post-intervention. The set of
available individuals at baseline and...

auto.arima and intervention analysis
Hello,
I'm currently using auto.arima to verify the order of my arima model. I
would like to use the model to conduct an intervention analysis. The problem
is that, when I include a step function in auto.arima, by including a binary
variable in "xreg", the arima order that auto.arima gives is different from
when I don't include it. From my understanding, the "pre-whitening" that is
required for interventio...

Annoying license at install
...over the phone), and then issue two commands
after the first boot. One was a 'curl' to download a script of mine,
and the second was a dot-command to run it. A few reboots followed
in close succession, and I directed them to logon as root, and issue
a simple dot-command. The personal intervention ended usually within
an hour, since I had ssh access to the system and root, and could
complete the installation and tailoring completely remotely. I would
only need their intervention in the case of problems. In many cases,
I've not needed to invoke that help for a year or more.

Arimax with intervention dummy and multiple covariates
Hi
I'm trying to measure the effect of a policy intervention (Box and Tiao, 1975).
This query has to do with the coding of the model rather than with the particulars of my dataset, so I'm not providing the actual dataset (or a simulated one) in this case, apart from some general description.
The time series are of length n=34 (annual observations betwee...

intervention analysis for time series
Dear all,
I am wondering how/if it is possible to implement the general
methodology
of Box and Tiao: "Intervention analysis with applications to economic
and
environmental problems" (JASA, 1975, pages 70-79) in R?
This question has been posted before but without a positive response

R codes for Intervention Time Series Analysis
Dear everyone, I need R codes to fit an Intervention Time Series Model for two separate policies for a single observed time series.
Please, I have prior knowledge of how to fit the impact parameter(omega) but I no not the codes for the decay parameter(delta). Can someone help me?

using metafor for meta-analysis of before-after studies
Greetings,
I wish to conduct a meta-analysis for which the outcome is a continuous
variable measured on the same individuals before and after an intervention.
Hence, the comparison is not made between two groups, but within groups, at
diffrent times.
Each study reports the mean outcome and SD before the intervention and the
mean outcome and SD after the intervention. While p-values for paired
t-test (or similar methods for paired data) are repo...

Run as root on reboot
Folks
Is there a way to reboot and have a script run without
intervention. During initial setup, I'd like to avoid the manual
actions of logging on as root and executing a command, but instead
have that command run without intervention. The output of the
command would still show up on the terminal that initiated the reboot.
Security is not a concern here. And...

Renewal of Let's Encrypt Certificates in Dovecot
Hi there. I've been using Dovecot for quite some time now but I just
started using Let's Encrypt certs. Since LE certs are renewed automatically
without user intervention I'm wondering if I will need to restart dovecot
after that renewal...
Has anybody had any experience with that?
Thanks so much for your help!

So for example, for each 6 person block, 4 would be assigned to intervention and 2 to control.

How do I confirm importing repo key without user intervention?
Hi,
Sorry for asking it again. I just thought I asked the question the
wrong way. Too much unnecessary details. And therefore, got no
replies.
I'm configuring a server from, say, a script (automatically). I need
it to be done without user saying, "Yes, it's okay to import the key."
I was told to run the following command:
yum makecache -y --disablerepo=*
