Hello,
I'm just learning how to use Eviews and have a newbie question. I've imported 14 years of daily panel data, and would like only to analyse the datapoints from Tuesdays to Fridays (excluding Mondays). I believe it is done through "sample" option, but I wasn't able to find any information on how to include only specific days of the week.

I have got a similar question, I have two work files, one with panel data and one with unstructured data. In both of these data sets I would like to create two samples. One in which my dummy variable equals 1 and another in which my dummy variable equals 0. The reason for this is that i would like to get separate regression outputs for multinationals, dm 1, and domestic companies, dm 0. I have tried (smpl if @dm=1), (smpl @dm=1), (smpl if @dm>0) and (smpl @dm>0). Non of the work. What am i doing wrong?

I would like to thank you in advance for your help.

How can I remove a specific date/dates from a sample? I've tried smpl if @date <>"specific date/s", smpl if @day <>"specific date/" (in the case of daily data), but it does not work. Also, I've tried to make 2 sub-sample: @first specific date-1 specific date +1 @last, but GARCH models require a continous sample.

Thank you.

How did you enter the specific dates?

GARCH does require a continuous sample.

Do you mean the format which I have entered the date? It's MM/DD/YYYY format.

You need to do:

Code: Select all

smpl if @date<>@dateval("mydate")

smpl if @date<>@dateval("mydate")
And for multiple dates?
