validation_preprocessor_dl() contain the following columns:
<table class="output">
<tr>
- <th>buffer_id</th>
- <td>INTEGER. Unique id for each row in the packed table.
+ <th>independent_var</th>
+ <td>BYTEA. Packed array of independent variables in PostgreSQL bytea
format.
Review comment:
We can also add that the independent var is first normalized and then packed
and converted to bytea. I understand that we already mentioned this in the
function definition. But I believe that it will be valuable to mention it again
just like we do for dependent_var
