Hello,
I want to calculate # of months with insurance.
The table below is for one person's records including start date and termination date.
I'd like to create # of months with insurance each year.
For this case, the final data that I want to have looks like below:
The red-colored year, 2043, can be interpreted as 2017.
Would you help me how to calculate # of months each year?
This is the 1st time I used dataex saved for Stata version 11 or 12. Array
Let me know if something is wrong with the data.
I deeply appreciate your help in advance,
Soyeon
