DESCRIPTION OF THE DATASET

A) THE SIGNAL TANDMOBIEL?DATASET

This is the data of the first year of the longitudinal Signal Tandmobiel? study (1996-2001) on Oral Health. There were 4468 children involved in the study, and 81 variables were recorded in total. In the paper, the dataset is referred to as the main or cross-sectional dental study.

Response: dmft, which is the sum of the number of decayed (d), missing due to caries (m) and filled (f) teeth in primary denition. Its values range from 0 to 20. The response is split according into:-

1 if dmft =0

2 if dmft =1

3 if 1

4 if 4

Covariates:the following covariates were of interest:-

- xcen,ycen: the tandardized form of the (x,y) coordinate of the municipality of the school to which the child belongs.

- age : the age of the children in years

- gender : the gender of the children, coded 0(boy) and 1 (girl)

- examiner : coded 1:16 for the 16 examiners, and 17 for the old standard

- schocode : an index of the schools to which the child belongs.

B) CALIBRATION DATASET

This is a validation data set containing information about the score for each of the 16 examiners against the gold standard. These data are 4 by 4 matrices for each examiner, with the columns (1-4) representing the gold standard score and the rows (1-4) corresponding to examiner's score.

DESCRIPTION OF THE PROGRAM

A WinBugs program was written to perform the analysis of the Bayesian ordinal logistic regression model to correct for Inter-observer Measurement Error. The program is split into two parts:

- Main Data Model : Sampling a Markov chain pertaining to the regression parameters using correction term sampled from the calibration model

- Calibration Data Model: A Markov chain Sampling the correction terms using the calibration data

NOTE: these two two Markov chains are processed in sequential manner, by the use of the 'cut' option in WinBUGS.
