Errors

[trandafile]

I'm trying to use the code.

This section: from statsmodels.tsa.seasonal import seasonal_decompose

decomposition = seasonal_decompose(df_sample['SP500'], model='additive', freq=30)
plt.rcParams["figure.figsize"] = [13, 7]
fig = decomposition.plot()

Gives these errors:
TypeError Traceback (most recent call last)
Cell In[53], line 3
1 from statsmodels.tsa.seasonal import seasonal_decompose
----> 3 decomposition = seasonal_decompose(df_sample['SP500'], model='additive', freq=30)
4 plt.rcParams["figure.figsize"] = [13, 7]
5 fig = decomposition.plot()

TypeError: seasonal_decompose() got an unexpected keyword argument 'freq'

What's the version of statsmodels package are you using?

I checked the docs for 0.14.2 and the keyword freq is changed to period.
So in the new version of library the code is:
decomposition = seasonal_decompose(df_sample['SP500'], model='additive', period=30)

Thanks a lot for your feedback. Now this section of the code is working. However, I get this error: ---------------------------------------------------------------------------
NotImplementedError Traceback (most recent call last)

NotImplementedError:
statsmodels.tsa.arima_model.ARMA and statsmodels.tsa.arima_model.ARIMA have
been removed in favor of statsmodels.tsa.arima.model.ARIMA (note the .
between arima and model) and statsmodels.tsa.SARIMAX.

statsmodels.tsa.arima.model.ARIMA makes use of the statespace framework and
is both well tested and maintained. It also offers alternative specialized
parameter estimators.

I've solved it using this code:

import pandas as pd
from statsmodels.tsa.arima.model import ARIMA
model = ARIMA(df_sample['y_log'], order=(1, 1, 2))
model_fit = model.fit()

print(model_fit.summary())
