MLE and MLEQuick (Cahill Software)
Cahill Software offers MLE++, a C++ class library for maximum
likelihood estimation. This offers greater flexibility than "canned"
routines. They also offer a menu driven package, MLEQuick, for
"discrete dependent variable models, censored and truncated models,
and survival analysis." Finally, Cahill Software can be hired for
contract programming, with a specialty in "statistical estimation
programs and simulation models."
