Interval estimations for parameters of Gompertz model with time-dependent covariate and right censored data (2012)
Journal Article
Kiani, K., Arasan, J., & Midi, H. (2012). Interval estimations for parameters of Gompertz model with time-dependent covariate and right censored data. Sains malaysiana, 41(4), 471-480

There are numerous parametric models for analyzing survival data such as exponential, Weibull, log-normal and gamma. One of such models is the Gompertz model which is widely used in biology and demography. Most of these models are extended to new for...

Gompertz model with time-dependent covariate in the presence of interval-, right- and left-censored data (2012)
Journal Article
Kiani, K., & Arasan, J. (2013). Gompertz model with time-dependent covariate in the presence of interval-, right- and left-censored data. Journal of Statistical Computation and Simulation, 83(8), 1472-1490. https://doi.org/10.1080/00949655.2012.662979

In this paper, the Gompertz model is extended to incorporate time-dependent covariates in the presence of interval-, right-, left-censored and uncensored data. Then, its performance at different sample sizes, study periods and attendance probabilitie...

Simulation of interval censored data in medical and biological studies (2012)
Journal Article
Kiani, K., & Arasan, J. (2012). Simulation of interval censored data in medical and biological studies. International Journal of Modern Physics: Conference Series, 09, 112-118. https://doi.org/10.1142/S2010194512005168

This research looks at the simulation of interval censored data when the survivor function of the survival time is known and attendance probability of the subjects for follow-ups can take any number between 0 to 1. Interval censored data often arise... Read More about Simulation of interval censored data in medical and biological studies.
