Another important avenue for further investigation is the possibility of combining these type
inference techniques with overloading.
4 Feigert (1979) actually recommended the use of ecological
inference techniques in further study of ticket splitting but lamented that valid methods did not exist at the time.
Upon reading Dowd's account on how close statisticians were to develop causal
inference techniques by themselves, readers might be tempted to conclude that the distinction between causal and statistical inference is perhaps unwarranted, and that the former is but a nuance of the latter.
Meier (Texas A&M), Brudney (Cleveland State), and Bothe (University of Wisconsin) introduce basic statistical analysis, probability distributions, statistical
inference techniques, and relationships between two or more variables.
The enormous amounts and types of knowledge often required for carrying out practical reasoning, and the variety of
inference techniques that are displayed by practitioners, and the need to arrive at conclusions rapidly--these issues that once were considered mere "engineering" issues turned out to have nontrivial theoretical content for AI.
