Dear all,
I am currently trying to conduct quantile regression in Zelig and it does not work out.
In the net I can find two vignettes:
Rq: Quantile Regression for Continuous Dependent Variables
http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.205.1968
quantile: Quantile Regression for Continuous Dependent Variables
http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.205.3837
Independent of which specification I use (model="rq"; model="quantile"), I get the following message:
** The model "rq" is not available with the currently loaded packages,
** and is not an official Zelig package.
** The model's name may be a typo.
I greatly appreciate any help
Best regards,
Philipp

Greetings,
I am attempting to run a gamma.mixed model on five imputed datasets from Amelia II. I used mi() to combine the datasets in the zelig run. As with some others, when I call the summary () , I receive the error
*Error in object[[1]]$result$call :
$ operator not defined for this S4 class*
I can get the summaries for each individual dataset,but I cannot retrieve the summary of the combined datasets. I can combine the datasets using Rubin's rules, but given this analysis will use several different models and plots,
having the combined results would be far simpler.
Thanks,

> LU2010 -> zelig(Result~ Wetland + Developed+ Grasses+Crops,
model="logit.gee", id="Location",corstr="exchangeable", data=y2010)
> LU2010$residuals
NULL
I am running Zelig 4.2-1 and using the "logit.gee" model link to fit a
model. I am trying to get a print out of the model residuals to use to test
for spatial autocorrelation; however, when I try to get the print out it
says null.
My model is. I do not get any errors when I run the model and I get
coefficients and cun run Wald test.
Any help or ideas would be greatly appreciated.
Hi All,
I think I'm having an issue either with setx() or sim()--not sure which
one. The zelig() command runs fine and summary(z.out) output has the
correct results--the same I get from lm(). Setx() and Sim() also both run
without a problem, but summary(s.out) prints without any actual results and
when I try to plot(s.out) I get an error saying there are no y values. The
output and my code are below. I feel like I'm missing something pretty
obvious here, but am about out of ideas. Thanks in advance for any help!
Cheers,
Laura
