Other Works

Tutorial: Maximum Likelihood Modellierung von Zähldaten
Tutorial on Maximum Likelihood Estimation (German)
Gives a very simple introduction on how to estimate parameters via the Maximum Likelihood method. There also is a distinct section of model selection with the Akaike Information Criterion. These techniques are related to a recent research problem, that is a statistical model of usability defect detection comprising unobserved misses and false alarms.
