Re: Calculating mean in panel data

I just like to display a table where the most important descriptive statistics are mentioned. Let me make myself clear with an example. I have for example a regression with the following form: Y = a1 X1 + a2 X2 + error term. I have removed the outliers from Y, X1 and X2. Now, I'd like to create a ta...

Re: Calculating mean in panel data

One other question, I'll post it here if you don't mind. When selecting one variable, you can calculate the stats by classification (for example if you have data for different firms for different years, you can calculate the mean for all firms for each year with this function). However, when selecti...

Thanks Gareth for your quick response. I added the excel and the eviews workfile. It's just a part from the database because it's too big. Our dataset also involves panel data, but this is of no importance to calculate the mean. In EViews, I import these data from excel (open foreign data as workfil...

Calculating mean in panel data

Hi, I have a somewhat strange problem when calculating descriptive statistics for a panel data set in EViews. The data set covers 4 years and 60 000 firms. I calculate the mean value for one variable for each year using the "stats by classication" function. However, the values calculated f...

Dummy variables with missing values

Hi, In our panel data we have a dummy variable that has a lot of missing values (approximately 60% of the values missing, the other 40% have the value 0 or 1). It's no problem to import these data (we import them from excel) but once they are imported, EViews seems to indicate that these values are ...
