Time series analysis

Hi all,

I have started a new project that is based on time series forecasting in which I am trying to use this methods:

But, while working on it I found couple of errors:

1. While writing the ARIMA code as follows and I found the following error:
   y_hat_avg = test.copy()
   fit1 = sm.tsa.statespace.SARIMAX(train1[‘Adj Close’], order=(2, 1, 4),seasonal_order=(0,1,1,7)).fit()
   y_hat_avg[‘SARIMA’] = fit1.predict(start = “2018-04-03”, end = “2018-06-08”, dynamic=True)
   plt.figure(figsize=(16,8))
   plt.plot(train1[‘Adj Close’], label=‘Train’)
   plt.plot(test[‘Adj Close’], label=‘Test’)
   plt.plot(y_hat_avg[‘SARIMA’], label=‘SARIMA’)
   plt.legend(loc=‘best’)
   plt.show()

Error:
KeyError: 'Thestartargument could not be matched to a location related to the index of the data.'

Please have a look at this and let me know how to solve this error.

Best,
