title: attributes of a model
body: <p>Can you kindly help me in the below query.
  I have a Time series model - SARIMAX and have a model ( Refer below code )</p>
  
  <pre><code>mod = sm.tsa.statespace.SARIMAX(y,
                              order=(1, 1, 1),
                              seasonal_order=(1, 1, 1, 12),
                              enforce_stationarity=False,
                              enforce_invertibility=False)
  
  results = mod.fit()
  </code></pre>
  
  <p>Now, i predict the forecast as </p>
  
  <pre><code>pred = results.get_prediction(start=pd.to_datetime('1998-01-01'), dynamic=False)
  pred_ci = pred.conf_int()
  </code></pre>
  
  <p>So, pred is my object with forecasted values. I wanted to know all the available attributes of the object - "pred"
  Like : pred.predicted_mean </p>
  
  <p>Kindly help</p>
