Figure 2 shows the fit of the regression model to the hazard function
The anticipated inverse relationship between asset size and the hazard of disappearance is evident in both of the hazard function
estimations, indicating that a smaller credit union was at significantly greater risk of disappearance through either acquisition or failure than a larger one.
It can be seen from Figure 2 that there is a factor of about four in the hazard range for the blue hazard function
over the wide range of color temperatures of the light sources shown, while for the lipofuscin function this range is reduced to about a factor of 2.
To model the hazard functions
for graduation after a given year in high school controlling for the effect of disability, I fitted a series of discrete-time hazard models (Singer & Willett, 2003).
13) The model is semi-parametric in the sense that the vector [beta] can be estimated without imposing any assumption on the baseline hazard function
Our specification follows Cox (1972); who assumes that hazard function
has a multiplicative form: h(t[x.
or the product of an unspecified baseline hazard function
The maximum of the hazard function
is reached at the age of 21.
If we define the hazard function
as h(t, x, [beta]) [equivalent to] f(t, x, [beta])/S(t, x, [beta]), where S is the survivor function S(t, x, [beta]) = [[PI].

In the second plot, we add `state' to this hazard function
: this generates a family of hazard functions
