Re: Combine @sumsby with sample command

The problem with your suggestion is that it sums up the values if skill=fishing over all states. What I need is that fishing and hunting are summed up in one state.

I solved the issue with a loop. However, it would be interesting to know if it was necessary.

Re: Combine @sumsby with sample command

I need to create a new series that sums up several observations at every point in time. In your example, that would be something like: series SUM = CA_fishing + CA_hunting but other skills in CA (e.g. CA_farming) must not be included in the summation. The series SUM then contains the same value for ...

Re: Combine @sumsby with sample command

That is not exactly what I need.

I have a state-skill combination as the cross-sectional dimension. Now I wish to sum up the values of a series for some of the skills in one state at one point in time.

Combine @sumsby with sample command

Is it possible to combine the @sumsby command with the sample command? I wish to sum over a subgroups in one period in a panel-data set.

Re: Sort regression output

As suggested, I created a dummy series for each period. However, now I cannot simply use something like

Code: Select all

time_fe*dummy


Is it really necessary to write a program to get the the interaction?

Re: Sort regression output

Quick follow up on this one: How can I specify a specific period instead of the first one? This @expand(@month*@year,@drop(@month*@year={number})) command produces the near singular matrix problem, it works fine if I use @dropfirst instead.{number} is the value of the product of @month*@year, e.g. {...

Sort regression output

I use the dummy*@expand(@year*@month,@dropfirst) command to interact a dummy with a bunch of time dummies. I was wondering if there is any way to sort the regression output without coping everything to Excel? Eviews sorts the output according to the product of @month*year which is rather useless if ...

Clustered SE

The White estimators described here http://www.eviews.com/help/helpintro.html#page/content%2Fpool-Pooled_Estimation.html%23ww187927%20allow%20clustering allow clustering over periods or cross sections. I believe the clustering takes place on the lowest level. Is it possible to cluster on higher leve...
