Irish Educational Transitions Data
----------------------------------
Below are shown data on educational transitions for a sample of 500
Irish schoolchildren aged 11 in 1967. The data were collected by
Greaney and Kelleghan (1984), and reanalyzed by Raftery and Hout (1985, 1993).
The data were also used, in a simplified form, as an example to illustrate
Bayesian model selection methods by Raftery (1988) and Kass and Raftery (1993).
In that simplified form, primary terminal leavers and cases with any missing
data were removed, leaving 441 cases. The Leaving Certificate variable
was used as the dependent variable in a logistic regression analysis.
The variables shown are as follows:
1. Sex: 1=male; 2=female.
2. DVRT (Drumcondra Verbal Reasoning Test Score).
3. Educational level attained:
1 Primary terminal leaver
2 Junior cycle incomplete: vocational school
3 Junior cycle incomplete: secondary school
4 Junior cycle terminal leaver: vocational school
5 Junior cycle terminal leaver: secondary school
6 Senior cycle incomplete: vocational school
7 Senior cycle incomplete: secondary school
8 Senior cycle terminal leaver: vocational school
9 Senior cycle terminal leaver: secondary school
10 3rd level incomplete
11 3rd level complete
4. Leaving Certificate. 1 if Leaving Certificate not taken; 2 if taken.
5. Prestige score for father's occupation
(calculated by Raftery and Hout, 1985). 0 if missing.
6. Type of school: 1=secondary; 2=vocational; 9=primary terminal leaver.
