### Coverting non-integer values to integer values

Hello,

Is there any way to convert non-integer values (2.3454 or 2.8733) to integer values (2 or 3) after rounding up or down? Any advice would be appreciated. Thanks.

### Calculating the Serial Correlation LM Test Statistics

Hello, I am using GARCH models. However, there is no built-in Lagrange multiplier (LM) tests in EViews 11 for serial correlation in the residuals. Below the codes I have used to conduct the LM test. equation eq1.ls sf c blm --> This is the regression of sf on a constant and the independent variable ...

### Re: Zero Inflated Possion/Negative Binomial Models

What is the difference between zero-altered and zero-inflated? startz, Based on my limited knowledge, both zero-inflated and -altered poisson models have two components: binary and county processes. However, they differ in terms of whether the count model is truncated at zero or not. Zero-inflated ...

Gareth, I could find the example file for zero-altered models but could not for zero-inflated models. Could you please direct me to the example file? Thank you.

### Re: RE: Authomatic ARIMA Forecasting

Dear Gareth, Following your suggestions, I conducted automatic ARIMA forecasting with a seasonal dummy variable and a lagged dependent variable, which gave me ARIMA (0, 1) as the best fitted model. Thus, I used ARIMA (0, 1) with the same model specification with the previous one to forecast with con...

I conducted automatic ARIMA Forecasting. Eviews provides a comparison graph between observed and forecasted values. I just wonder whether Eviews provides confidence intervals for forecasted values. I would appreciate any help.

You cannot. Although, of course you could just create a series equal to 5.25 on the periods you want, NA everywhere else, and then add that series to your graph. Thank you for your response. I do not quite understand what "NA everywhere else, and then add that series to your graph" means....
