We propose a new parametric time-varying shared frailty model to represent changes
over time in population heterogeneity, for use with bivariate current status data.
The model uses a power transformation of a time-invariant frailty <i>U</i>, and is
particularly convenient when <i>U</i> is a member of the generalized gamma family.
This model avoids some shortcomings of a previously suggested time-varying frailty
model, notably time-dependent support. We describe some key properties of the model,
including its relative frailty variance function in different settings and how the
model can be fitted to data. We describe several applications to shared frailty modeling
of bivariate current status data on infectious diseases, in which the frailty represents
age-dependent heterogeneity in contact rates or susceptibility to infection. |
