EPP takes as input a file organised as follows. Each line in this file is a distinct entity. Four kinds of lines are understood:
The first field on each line of input determines the line type. The options are:
comment | This line appears in the generated table as a comment |
estimate | This line appears in the generated table as a parameter estimate |
caption | This line is the table caption |
blank | A extra blank line in the table. |
Only the first two letters are matched, so these shortforms are allowed: co, es, ca, bl.) On comment lines and on the caption line, the remaining fields are treated as words which make up the comment/caption.
On parameter lines, there are three more pieces of information:
Field 2 | label (a string with no spaces in it) |
Field 3 | free or not (Was it being estimated?) |
Field 4 | parameter estimate |
Field 5 | standard error (need not be present when it was not free) |
