hi, eva,
when i ran your code i found a misspell:
result = statsmodels.tsa.statools.adfuller(x,1)
when i fixed 'stattools' --
result = statsmodels.tsa.stattools.adfuller(x,1)
print result
(-2.6825663173365015, 0.077103947319183241, 0, 7, {'5%': -3.4775828571428571,
'1%': -4.9386902332361515, '10%': -2.8438679591836733}, 15.971188911270618)

Subject: [Tutor] i installed the package statsmodels but i get an error when
i use it
Good afternoon,
I installed from https://pypi.python.org/pypi/statsmodels the package
statsmodels for python 2.7 (32bit) , i have to do some test statistics for a
time series analysis that i can find under statsmodels.tsa. In particular i
really need to do a Dickey Fuller test and in agreement with the statsmodels
documentation ( from
http://statsmodels.sourceforge.net/devel/generated/statsmodels.tsa.stattools.adfuller.html
) i run this simple programm
import numpy as np
import statsmodels
from statsmodels.tsa import stattools
x = np.array([1,2,3,4,3,4,2,3])
result = statsmodels.tsa.statools.adfuller(x,1)
print result
but unfortunately i get the following error message:
Traceback (most recent call last):

ImportError: C extensions not built: if you installed already verify that you
are not importing from the source directory
the thing that i really don't understand is that in the shell window if i type
import statsmodels.tsa i don't get any error, also if i type the help funcion i
can see that in the package there is the function stattools that i need
>>> import statsmodels.tsa
>>> help(statsmodels.tsa)
