I imported statsmodels.tsa.stattools so I could use the act() function. From the documentation, the function is called as follows:
statsmodels.tsa.stattools.acf(x, unbiased=False, nlags=40, qstat=False, fft=False, alpha=None, missing='none')
However, when I specify all the parameters, I get this error:
TypeError: acf() takes at most 6 arguments (7 given)
Clearly there are 7 in the definition. The problem seems to be with the last argument, which is crucial for handling missing data.
The module may need to up updated, since
stats models.__version__
gives '0.6.1' as the result, but 0.8.0 is current.
Suggestions?
