Try this query

select id, value, (select count(*) from tbl b  where a.id >= b.id) as cnt
from tbl a

FIDDLE

| id | value | cnt |
--------------------
|  1 |   yes |   1 |
|  3 |   yes |   2 |
|  4 |   yes |   3 |
|  6 |   yes |   4 |
|  9 |   yes |   5 |

SQLite Release 3.25.0 will add support for window functions

2018-09-15 (3.25.0)

Add support for window functions

Window Functions :

A window function is a special SQL function where the input values are taken from a "window" of one or more rows in the results set of a SELECT statement.

SQLite supports the following 11 built-in window functions:

row_number()

The number of the row within the current partition. Rows are numbered starting from 1 in the order defined by the ORDER BY clause in the window definition, or in arbitrary order otherwise.

So your query could be rewritten as:

select *, ROW_NUMBER() OVER(ORDER BY Id) AS NoId
from data 
where value = "yes";

I mended somewhat with fiddleanswer and got exactly the result as expected

select id, value , 
       (select count(*) from data b where a.id >= b.id and b.value='yes') as cnt 
from data a where  a.value='yes';

result
1|yes|1
3|yes|2
4|yes|3
6|yes|4
9|yes|5
