Hello everyone,

Can someone really help me out? I badly need help!

I am doing out-of-sample forecast. Following is my program: As a forecast evaluation test, I also want to check the Theil statistics. I have tried with @theil command but is unable to find the appropriate result.

Please help me out with the problem.

Best,
Saakshi

All of the forecast evaluation type statistics (@rmse, @mse, @mape, @smape, @theil) work as: where y_* are series objects.

Hello Gareth, thank you for help.

I did post the command but was unable to generate the result. Following is the command file. Kindly let me know where am I making mistake.
Gareth, I am very new to the command program, so kindly help me out this.

Thanks,
Saakshi

You don't appear to be storing the theil statistic anywhere.

HORIZON h=1 h=2 h=3 h=4
Bias 0.522 1.026 1.434 1.591
MSE 3.136 5.300 8.923 12.197
RMSE 1.771 2.302 2.987 3.492
SE 1.692 2.061 2.620 3.109
MAE 1.486 2.000 2.466 2.525
MAPE 0.664 1.051 0.910 0.648
THEIL 0.000 0.000 0.000 0.000

This is my result window.

Where should I store the statistics ideally?
Am I missing something here?

Hello, I understand this must be a very simple question but I am in the learning phase and I badly need your help.

kindly help!

All of the forecast evaluation type statistics (@rmse, @mse, @mape, @smape, @theil) work as:

Code: Select all

!mystat = @theil(y_actual, y_forecast)

where y_* are series objects.

Hi Gareth,

I am trying to write following command for Theil. Could kindly you tell me what mistake is in this?
THEIL=@sqrt(RMSE)/@sqrt({%v}-{%v}(-1))*@sqrt({%v_f}-{%v_f}(-1))

Thanks,
Saakshi

I see nothing wrong.
