Looking at the code for the crq function it appears that with method=Portnoy
the tau value is not passed to the fitting function (crq.fit.por) and that

calculate the grid of tau values given the nature of the
Dear Michael,
Thank you for your comment. My difficulty is concerned with the high
coefficient of the independent variable. The result I get fro running a logit
regression is:
ylog e^x= -3.3499+ X4.4738. Changing the numbers to exponents of e (antilog) to
better interpret the results, I get y
Peter,
Appreciate the comment. Here is a summary table. Both variables (Profit and
dividend with 0=yes 1=no) are binary as pointed out. I have out of 368
companies of which 342 were profitable and 26 unprofitable. Of the 342, 79 paid
no dividends and 263 paid dividends. Of the 26, 25 paid no
In the ca package, the summary method gives the following output, as a

Hi,
I am tasked with making a map of German postal codes for a few major cities
in Germany. Each postal code will have a differnt color, depending on a
metric. For simplicity, let's just use population density.
This is what I have achieved so far for London (which I used as an
example). I have

Hi Paul,
Have you seen this site?

This seems to have the solution you want, and perhaps some useful
stuff about aggregating postal zones. For one off maps, I usually just
look at par(usr) to get the current plot
Hi Allen,
Thanks for your response. Regarding the issue that Portnoy and PH estimators
may not compute parameters in the tail, I believe this is dependent on the
amount of censoring (e.g., in the extreme case, if all observations are
censored in the upper tail, one cannot obtain estimates in

Hi,
For your error object 't1971' not found can be corrected by subsetting.
t2001 can be done similarly with 2001 replacing 1971.

Hi,
I think that putting all your objects into one single list would be
easier, both to handle it and to save it.
To do it, you can create an empty list with 1000 elements before running
your function and then run your function in a loop (or something
similar) with the output of each run

Hi:
You get a gradient for your response variable because it is numeric.
You need to convert it to factor. (Discrete color sets need to be
mapped to discrete variables - a factor is one way to generate a
discrete variable.) Here is one approach to get what you appear to be
looking for.
