| الملخص: | In survival analysis, itâ��s known a hazard function. Itâ��s a risk or rate of an individual get
an event with one conditional, that individual survives until an event occurs. The hazard function
may depend on observed risk variables but usually not all variables are known or measurable.
This unknown factor of the hazard function is usually termed the individual heterogeneity or
frailty. In its simplest form, a frailty is an unobserved random factor that modifies
multiplicatively the hazard function of an individual or group or cluster of individuals. In this
thesis will be discussed about lognormal frailty model, an extension of Cox regression.
Hierarchical likelihood method will be used to estimate the regression coefficients and to find the
effect of frailty in the two level survival data. |
