piecewise linear regression
We sent questionnaires to lots of folks. The questionnaires
differed in word count (wc). For each questionnaire, I know wc
and whether the questionnaire was returned or not (status). It
looks like there is a fixed rate of return when wc is below a
break point, and the rate of return falls off linearly after
that.
I want to do a piecewise linear regression with two pieces

Compare data between two groups/countries on 5-point Likert scale questionnare?
Hi everyone, I'm stuck on my dissertation which is due next week. I'm a
business major student and my project is a comparative research on corporate
social responsibility (CSR) between Chinese and German firms. According to
my literature review, it's quite obvious that German firms have much better
CSR initiatives and strategies than the Chinese ones and I wanted to test
whether it was

Is there a better way for inputing data manually?
Dear All,
I have worked with R for some time. It's a great tool for data analysis. But it's too hard to inputing raw data manually with R (I don't mean importing data. R is good at importing data). Maybe it's not a focused topic in this list, but I don't know other place where I can ask the question. How do you do when inputing data from a paper material, such as

Remove missing observations
Hi everyone
I have the following problem: My dataframe has 3 variables: ID, Year and
and an outcome variable. The dataframe contains repeated measurements
because the subjects filled out a questionnaire every year. The time span
covers 2 years.
Now I want to check if there is a significant change in the outcome over
the 2 years with a paired wilcox.test. The problem: Not every subject

Another NEWBIE
Hi,
I'm a very fresh newbie to R.
My first main question is, what the limitations of R are, what methods can R
NOT do, esp. compared to (a) SPSS and (b) SAS?
The second question is, how do you handle the data entry, data management
and data manipulation in R, to me it seems to be really complicated and
confusing?! Are there a kind of "helping tools"?
The third question: are

Repeated measures logistic regression
Dear all,
I'm struggling to find the best (set of?) function(s) to do repeated
measures logistic regression on some data from a psychology experiment.
An artificial version of the data I've got is as follows. Firstly,
each participant filled in a questionnaire, the result of which is a
score.

How should I organize data to compare differences in matched pairs?
I'm just learning how to use R right now, so I'm not sure what the most
efficient way to organize these data is.
I had subjects perform the same task twice with slight changes between the
rounds. I want to analyze differences between the rounds. All of the
subjects also answered a questionnaire.
Putting all of one subject's information on one row seems sloppy.

Questionnaire Analysis virtually without continuous Variables

different districts of some mysterious foreign country. The aim of the

success of a peculiarly beautiful bird in that area. All variables are
factors, i.e. they are variables such as "Use of Guns - yes / no", "Use

using survey weights for correlations
Dear list,
I have a data file which includes, alongside various variables representing questionnaire scores, a variable for survey weights computed as the number of observations in the sample drawn from that group divided by the number of observations in the population in the group. I need to calculate a covariance matrix of the questionnaire scores for use in sem. How do I apply the weights?

Rating R Helpers
Since R is open source and help may come from varied levels of
experience on R-Help, I wonder if it might be helpful to construct a
method that can be used to "rate" those who provide help on this list.
This is something that is done on other comp lists, like
