5.2. statsmodels.sandbox.cox¶
Cox proportional hazards regression model.
some dimension problems fixed import errors currently produces parameter estimate but then raises exception for other results
finally, after running the script several times, I get a OSError with too many open file handles
updates and changes :
as of 2010-05-15 AttributeError: ‘CoxPH’ object has no attribute ‘cachedir’ Traceback (most recent call last):
- File “C:...scikitsstatsmodelssandboxcox.py”, line 244, in <module>
- res = c.newton([0.4])
AttributeError: ‘CoxPH’ object has no attribute ‘newton’
replaced newton by call to new fit method for mle with bfgs
feels very slow need testcase before trying to fix
