just a recurrent Warning
Every once in a while google groups puts a message, even from an
accepted member of the list, into the spam filter without notifying
Skipper and me.
If you send a message, and it doesn't show up on the google group
within a reasonable time (and it's not spam), then ping me or Skipper... more »

pypi download statistic Robots ?
|
| |
Just trying to see if anyone knows?
I just realized that TravisCI is downloading packages from pypi at each run.
does this count in the pypi download statistic?
That could inflate the numbers pretty much, if other packages have a
package as dependency.
TravisCI is downloading zip files, which might explain some of the zip... more »

TravisCI problems with python-dateutil - is there an apt-get?
|
| |
We are seeing recently sometimes build failures on TravisCI because of
pandas dependencies not being available.
Is there a pre-packaged version for python-dateutil, that we don't
have to rely on labix.org large web page to be available fast enough?

Standard errors for Poisson regression
|
| |
By now I have a guilty feeling, costing you guys so much time in going through my comments. Please tell me when to stop! Problem This time it is the standard errors for Poisson regression that don't match up. The fitted parameters, as well as the "fittedvalues" are pretty close (I guess that the mis-matches are just differences in when to stop the... more »

observations for multiple labels on the same day, I would like to select
the row or rows that meet a given criteria. I the data below I would like
to select A12 until November 6th and then use B12 after that. One way to do... more »

errors in for nominal logistic regression?
|
| |
In comparing the output of the statsmodel MNLogit function with results from R and STATA, I ran into two questions/problems: 1) While the absolute values of the fitted parameters and the standard errors match, the sign differs from that in R: the R-command "multinom" from the library "nnet" res.cars=muninom(c_resp~factor (c_age)+factor(c_sex), weights-freq,... more »

nominal logistic regression with formula/patsy
|
| |
Is is possible to do a nominal logistic regression with a formula/patsy in statsmodels? And what about setting the frequencies? In R, one can set the frequency in "multinom" (in the library "nnet") with the parameter "weights=freq". In statsmodels, I currently somewhat clunkily hand-generate the endog- and... more »
