mle is a simple programming language for building and estimating parameters of likelihood models. The language was originally intended for building and estimating parameters of survival models, but the language has evolved to be general enough to estimate parameters for many other types of likelihood models. Indeed, the language attempts to be a general purpose tool for likelihood estimation.
The program is free for non-commercial use, and can be downloaded from this site.

Note that the 32-bit versions will work on the corresponding 64-bit operating system, but my execute slightly slower (I haven't benchmarked this yet. Also, a 64-bit Windows version has not been released on account of bad behavior upon dividing by zero.

Windows Vista (and Windows 7) users are encouraged to upgrade to 2.2.16.
How do you upgrade with a beta version? For Windows users, start by installing the official release using the install package, if you haven't already done so. Then, download the beta executable (say, mle2_2_16.exe) and rename it mle.exe and save it over the existing mle.exe in the install directory (this is frequently C:\Program Files\mle\mle.exe). Linux users follow a similar procedure. Install the package (if it hasn't already been installed), and replace the existing mle executable by downloading the beta version (say, mle.2.2.16.linux.i386) and renaming it to mle.1 May 2006. The Crimson Editor is great little text editor for Windows that can also act as a development environment for mle. The editor provides syntax highlighting, will execute mle programs from within the editor, and provides help for keywords. If you want to use the Crimson Editor with mle, see this page.
