Firstly, I have read Werner's answer to "! Misplaced \omit" error but my problem is not solved there.
A few days ago I made a table very similar to the one below, except that one had one less row and column. There were no problems. Now I get an error. This monstrosity was created using esttab, a tool that exports STATA regression tables to latex.
Relevant part of my preamble:
%---------TABLES---------
\usepackage{booktabs}
\usepackage{tabu}
\usepackage{threeparttable}
\usepackage{multirow}

The error I get is
Error in thesis.tex (line 351): Misplaced \omit.
\multispan ->\omit \@multispan l.351 } I expect to see \omit only after tab marks
or the \cr of an alignment. Proceed, and I'll ignore this case.
line 351 is towards the end of the table:

Everything renders out fine and looks great, but I really hate creating a document with errors.

Of course several improvements can be done to the input, but the main problem is that one.
Use a “divide and conquer” method: I commented out all lines of the table and started uncommenting them one by one until the error appeared. Then I knew what line was the culprit and found out why.
