Osteoporosis is a systemic skeletal disease characterized by low bone mass and deterioration of bone microarchitecture that result in bone fragility and susceptibility to fracture. 1 Positive family ...

Although nonparametric analyses of bivariate failure times under independent censoring have been widely studied, nonparametric analyses of bivariate competing-risks data have not yet been investigated ...

Frailty models have emerged as a pivotal tool in survival analysis, offering a robust framework to account for unobserved heterogeneity and dependence between paired failure times. In bivariate ...

A procedure for estimating a bivariate density based on data that may be censored is described. After the data are transformed to the unit square, the bivariate density is estimated using linear ...
