The breast cancer data from Finkelstein (1985) has been analyzed
extensively for illustrating new methods in modeling interval censored
data. The objective of the study was to compare the time to cosmetic
deterioration between two groups: 46 patients receiving radiotherapy only
and 48 patients receiving radiotherapy plus chemotherapy. Because the
detection of deterioration required a clinic visit, the 56 women who
experience deterioration were interval censored, and the other38 women who
did not were right censored.

datasets

Time-varying coefficient models for interval censored and
right censored survival data including
1) Bayesian Cox model with time-independent, time-varying or
dynamic coefficients for right censored and interval censored data studied by
Sinha et al. (1999) <doi:10.1111/j.0006-341X.1999.00585.x> and
Wang et al. (2013) <doi:10.1007/s10985-013-9246-8>,
2) Spline based time-varying coefficient Cox model for right censored data
proposed by Perperoglou et al. (2006) <doi:10.1016/j.cmpb.2005.11.006>, and
3) Transformation model with time-varying coefficients for right censored data
using estimating equations proposed by
Peng and Huang (2007) <doi:10.1093/biomet/asm058>.
