Tandmob: Signal Tandmobiel data

Description

This is the dataset resulting from a longitudinal prospective dental study performed in Flanders (North of Belgium) in 1996 -- 2001. The cohort of 4 468 randomly sampled children who attended the first year of the basic school at the beginning of the study was annualy dental examined by one of 16 trained dentists. The original dataset consists thus of at most 6 dental observations for each child.

The dataset presented here contains mainly the information on the emergence and caries times summarized in the interval-censored observations. Some baseline covariates are also included here. This is a copy of tandmob2 data in the package bayesSurv.

For more detail on the design of the study see Vanobbergen et al. (2000).

This data set was used in the analyses presented in $\mbox{Kom\'{a}rek}$ et al. (2005), in Lesaffre, $\mbox{Kom\'{a}rek}$, and Declerck (2005) and in $\mbox{Kom\'{a}rek}$ and Lesaffre (2007).
