DOI: 10.1002/sim.9363
Abstract: We propose a two‐way flexible cure rate model. The first flexibility is provided by considering a family of Box‐Cox transformation cure models that include the commonly used cure models as special cases. The second flexibility… read more here.

DOI: 10.1080/02664763.2024.2337086
Abstract: We construct a new partially linear regression based on a reparametrized generalized gamma distribution with two systematic components that can be easily interpreted. Its parameters are estimated by penalized maximum likelihood. For different parameter settings,… read more here.

DOI: 10.1080/03610926.2018.1429630
Abstract: ABSTRACT Consider two parallel systems with their independent components’ lifetimes following heterogeneous exponentiated generalized gamma distributions, where the heterogeneity is in both shape and scale parameters. We then obtain the usual stochastic (reversed hazard rate)… read more here.

DOI: 10.1177/0962280217690770
Abstract: Conditional two-part random-effects models have been proposed for the analysis of healthcare cost panel data that contain both zero costs from the non-users of healthcare facilities and positive costs from the users. These models have… read more here.
