NameError

[chrifels]

I am quite new in Python ...

When I run your ARMA-Code in Jupyter Notebook, I get an error after block [9] (i.e. acf_vals = acf(first_diff) .....):

NameError Traceback (most recent call last)
in
1 acf_vals = acf(first_diff)
----> 2 plt.bar(range(num_lags), acf_vals[:num_lags])

NameError: name 'num_lags' is not defined

May be you could check it.

Thank you,
Christian

num_lags = 10
acf_vals = acf(first_diff)
plt.bar(range(num_lags), acf_vals[:num_lags])
