I would like to assign ascending count for observations above certain value by id and start with the first observation of the id by 1 regardless of the value and continue the count if value is above 5 the output would be like:
id | days | event_count |
A | 1 | 1 |
A | 5 | 0 |
A | 2 | 0 |
A | 4 | 0 |
A | 7 | 2 |
A | 5 | 0 |
A | 8 | 3 |
A | 2 | 0 |
A | 1 | 0 |
A | 16 | 4 |
B | 1 | 1 |
B | 5 | 0 |
B | 2 | 0 |
B | 4 | 0 |
B | 7 | 2 |
B | 5 | 0 |
B | 8 | 3 |
B | 2 | 0 |
B | 1 | 0 |
B | 16 | 4 |
B | 4 | 0 |
B | 5 | 0 |
B | 3 | 0 |
B | 4 | 0 |
B | 7 | 5 |
B | 8 | 6 |
B | 8 | 7 |
Thank you.

by id;
if first.id then count=1;
if days>5 then count+1;
if days>5 or first.id then event_count=count;
else event_count=0;
drop count;
