Hi,

The Analysis ToolPak was written by another company for Microsoft years and
years ago (the 1980's?). You might contact Microsoft, but it may be futile.

Or you might try running a password cracker aganst the add-in and then look
at the underlying code. I sure someone has made a routine to crack add-in
passwords.

Does anyone know what the underlying formula/macro is that this function uses
to determine bin size. I have a normal distribution for which I am using a
formalized calculation to determine the bin size, but it is not turning out
to be optimal. I tried using the histogram function and it produces bin
sizes that are ideal. Now I would like to incorporate this process into my
calculation of bins. Any suggestions?
