[Gretl-users] Generalized Methods of Moments in Gretl

Hi, Thank you for developing a great package. I do enjoy using Gretl. I have a query and some suggestion: Query: Are you planning to develop a GMM module in gretl? GMM is increasingly popular amongst economist, see Hayashi(2001) and Alastair R. Hall (2005). Suggestions: 1. Importing of Excel and other non-Gretl data file should be more flexible. I tried importing an Excel file without headings and could not. Have to type in headings before import. 2. Very often, I add new variables by defining the variables myself. But this is 2-3 layers down the menu.Possible to Define New variables up one level? 3. Heteroskedasticity-correction should apply to panel models or pooled models as well (may wish to take a leave from Eviews 5). 4. Aspects of panel data modules could be improved, making it easier to do fixed effect and random effect.Panel data is very popular nowadays. 5. Running White's tests for heteroskedasticity often crash the program. I would be happy to elaborate on above if required. Thank you and have a nice day regards chee kian __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
