Hello and happy 2009,
     Can someone explain to me (hopefully with more words than
equations) what multiplicative bias is?  It is one of the statistics
generated by the MET PointStat tool in the cnt (continuous statistics)
output file.  I tried looking it up with Google and Wikipedia, but did
not find an explanation.

Thank you,
