Create a variable that is equal to 1 if "the below value" bigger than "the above value"

[Jeon Joan]

Hello.
I'd like to ask for help.
I want to make goal, goal_pre, goal_post using by id and target.

To create a goal
in target, if "the below value" bigger than "the above value", it has 1.

To create a goal_pre
The value of goal goes up one by one.

To create a goal_post
The value of goal goes down one by one.

What should I do?
Thank!

No time variable?

[Jeon Joan]

Dear Nick Cox
I have "weekly" time variable
for example, "01dec2019" means "First week of December 2019"
but, STATA recognize as "daily" and time variable is not continuous.
So I thought it was hard to use a time variable.
