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.

Is this not what you want? Screenshot 2021-01-11 061307.png startz, thank you for your response. Based on my knowledge, both zero-inflated and -altered negative binomial models are similar but differ in terms of whether the negative binomial component is truncated at zero or not. In addition, the w...

Search Help for Poisson. Negative binomial models are built in and there is an example file for zero-inflated Poisson. startz, thank you for your response.

Zero Inflated Possion/Negative Binomial Models

Hello,

I tried to build zero inflated possion/negative binomial models but could not find options in Eviews. Would you please direct me to the information on how to estimate them? Any help would be appreciated.

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...

Would you please provide me with any manual link for your procedures?

RE: Authomatic ARIMA Forecasting

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.

Re: RE: Draw Lines

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....

RE: Poisson and Overdispersion

Hello, I am going to conduct interrupted time series analyses with a 'count' dependent variable. I ran poisson regression of fatalc on independent variables. Then, I obtained the fitted values of the dependent variable and conducted a regression based test of the Poisson restriction using the equati...
