Hello,
I am a new user of Python. I have a couple of questions that would appreciate
your guidance!
* QQ Plot in Python: I could not find any functions in either Numpy or Scipy
to do QQ Plot of two vectors of data. For example, in Matlab, one could just
call qqplot(X,Y), which will generate the QQ plot of vector X against vector Y.
Would you please let me know which python package has similar functionality?
* Noncentral Chisquare: it looks to me that in Numpy and Scipy, the
noncentral chisquare distribution only allows Integer degree of freedom. For
example, the following code will produce an error message. In R, however, it
also allows non-integer degree of freedom. Would you please let me know which
python package has similar functionality?
* data = numpy.random.noncentral_chisquare(0.5, 2, 100)
* ValueError: df <= 0
Thank you very much,
Regards,
Chuang
