I'm working with panel data comprising several years of observations of schools. My DV is a proportion of exam passers but is not normally distributed, and many observations of the DV are > 0.8. A panel linear model using
plm() (from package
plm) is therefore inappropriate, so I am trying to treat the DV as a binary response and use logistic regression with
pglm() (from package
pglm). I have counts of the numbers of test takers and passers.
I have determined that I need to use fixed effects (within-unit) estimation for these data as I'm interested in the average change in exam pass rates within schools. I have far too many observations to post the full dataset but here is a small reproducible example of the error message:...

The error message about duplicate row names is a bit misleading as
pglm cannot handle the specific input
glm can handle with a two-column matrix specifying the proporion (
cbind(passers, fails) in your code).
glm is more flexible regards the various input possiblities, see
pglm can only handle a binary dependent variable as input on the left-hand side of the formula. Thus, you want to bring down the data to the "individual level" (Here is some better discussion of the topic with individual outcome (binary response) and group outcome (proportion), using glm http://www.simonqueenborough.info/R/statistics/lessons/Binomial_Data.html; http://pages.stat.wisc.edu/~mchung/teaching/MIA/reading/GLM.logistic.Rpackage.pdf).
Here is some code that gives you the data transformation to replicate the model you estimated using
pglm. See how the total number of exam
fails) is used to bring the data down to the individual outcome (binary
response) from the group level (
I have a dataframe with group and time-id. Now I want to create a new count variable, called
X2, conditional on previous values of
X1 within each group.
Suppose I have the following dataframe, variables
X1, and want to create
X2. The value of
X2 should be a count variable indicating the number of periods (i.e., rows) since
X1 has last been equal to 1 within the given group. If all previous values of
X1 are 0,
X2 should be missing.

This is a common problem, and no matter how precise you try to be, the computer will need to round numbers with repeating decimals at some point. Here's some posts that deal with it:
- How to make rounded percentages add up to 100%
- How to deal with the sum of rounded percentage not being 100?
In those posts you can read about many complex ways to get very close to 100%, but basically there is no right way to do this - when it's all boiled down it's still going to be an estimate - not exactly precise because we're dealing with not-precise numbers. That's just the nature of the beast.
Your program is going to round numbers the wrong way because it's a computer, and it's not intelligent.
Depending on your application, you may want to invest time into reading how to do those complex methods, and maybe you'll get really close.Add a Footnote
Any path you choose, you'll probably end up putting a footnote explaining this problem anyway. Something like this:
*Because of rounding, these values may not add up to 100%.

dotnet publish builds the project before copying binaries to the output directory. The files you see in
bin\Release\netcoreapp2.0\win-x64 directory are the result of
dotnet build command. You could check it by running following command:
dotnet build --configuration Release --runtime win-x64
You will see exactly the same files as if you run
dotnet publish --configuration Release --runtime win-x64.
Output binaries provided by build stage are then copied to publish directory together with required dependencies. You probably could expect that binaries are built right away to publish directory without necessity to duplicate them from build directory to publish. Well, it's a fair assumption. However it will harm separation of different stages - build and publish. Also as far as HDD resource is very cheap now, it shouldn't be a big issue.

You can use time-id like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the time-id component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
