To download the SOFA Statistics from the server I use the wget command:
wget -c http://sourceforge.net/projects/sofastatistics/files/latest/download?source=dlp
The filename of downloaded file in this case is download?source=files. If I add the --output-document option to the command, to rename the output file to sofastatistics-latest.deb, the format of downloaded file is not recognized by dpkg package.
dpkg-deb: error: `sofastatistics-latest.deb' is not a debian format archive
How to rename correctly the downloaded file with wget?
UPDATE - Jan 08 '15
With the provided link the downloaded file always will be a *.tar.gz one. To get it with the real name just add the --content-disposition option as this (thanks to @6EQUJ5!):
wget --content-disposition http://sourceforge.net/projects/sofastatistics/files/latest/download?source=dlp
But I needed a *.deb file, so here was right the @creaktive, I had to search for a *.deb file link.
Thanks to all for the answers!
A redirect of standard output into arbitrary file name always works. You are doing it correctly as man wget says, using -O
wget http://www.kernel.org/pub/linux/kernel/README -O foo

Indeed, you must be getting an HTML in your file (usually can be checked with man file).
[EDIT]
In your case client is receiving 302 Found (you can check it with curl -v URL).
The following curl does the trick by respecting the 3xx:
$ curl -L http://sourceforge.net/projects/sofastatistics/files/latest/download?source=files -o foo.deb

There should be similar option for wget to tolerate HTTP redirects.
If you were to do the same download from a web browser, and you notice the browser actually naming the file correctly, you can use the --content-disposition option to give wget the same behaviour:
wget --content-disposition http://sourceforge.net/projects/sofastatistics/files/latest/download?source=dlp
My Debian man page reports this as an 'experimental' feature but I cant recall it not working for me:
--content-disposition
If this is set to on, experimental (not fully-functional) support for "Content-Disposition" headers is enabled. This can currently result in extra round-trips to the server
for a "HEAD" request, and is known to suffer from a few bugs, which is why it is not currently enabled by default.
This option is useful for some file-downloading CGI programs that use "Content-Disposition" headers to describe what the name of a downloaded file should be.
That link points to a redirector, not the final destination! So you're downloading HTML and renaming it to .deb. The cluttered page has this around the top:
Your download will start in 0 seconds... Problems with the download? Please use this direct link, or try another mirror.
Now, this is a valid link (note the download prefix):
http://downloads.sourceforge.net/project/sofastatistics/sofastatistics/1.3.1/sofastats-1.3.1-1_all.deb?r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Fsofastatistics%2Ffiles%2Fsofastatistics%2F1.3.1%2F&ts=1358119361&use_mirror=ufpr
Pass this URL to wget.
Also, note that SourceForge tries to outsmart you, guesting the operational system via the User-Agent string. The best guess for "wget" seems to be the .tar.gz package. So, you should be more specific, requesting the deb file!
