CI of time series forecast in diagram

[Thomas Haug]

Hello!

I have made a forecast for a time series using the forecast command. I would like to produce a diagram that shows the time series with a CI (confidence interval) for the forecasted periods.
I have consulted the manual on the forecast command however I have not been able to produce the CI around the forecasted periods. I have tried using the tsfcastgraph, however with no success so far. Can anyone give me a hint on which command and extension I should be using? Thank you for any comments or advice.

These are the commands I use:

tsset time
reg x y z
estimates store x1
forecast create x_model, replace
forecast estimates x1
forecast exogenous y z
forecast solve, prefix(f_) begin(11)
twoway (tsline f_x)

I have time series data for two variables (y and z) for periods 1-40, and for periods 1-10 for the variable x.
I create a forecast for the periods 11-40 for x, based on the historical data of variables y and z.

Best regards
Thomas

You'll increase your chances of a useful answer by following the FAQ on asking questions - provide Stata code in code delimiters, readable Stata output, and sample data using dataex.
I'm afraid I don't use forecast, but a restated question might attract attention from someone who does.

Ok, thank you for the advice Phil!
