Hello!

I have 5 variables with approximately 60 000 observations for each, and I would like to split each variables into 2 variables , with one containing 75% of the observation and the other one accounting for 25%, so that I can use those 25% of observation to make an hold out sample.

Thanks you very much!

Perhaps just and later

I don't have a clue how to enter it into eviews

For example, how should I do it if my variable is called "activity" ?

Thanks for your help anyway
