Potential AMD hazard spectra: The oldest of these potential AMD hazard spectra is the blue hazard function that was developed from studies, mostly of primates, that showed retinal damage can occur with deep blue light, albeit at exposure levels far higher than levels typical of interior, or even normal exterior exposure.

Given a certain f(t) it is possible to determine h(t), and we can write the hazard function as h(t, [theta], x) where [theta] represents the actual parameters to be estimated.

Although the shape of the fitted hazard function differs by disability type, many students in each disability category still graduate after 4, 5, or 6 years.

The Cox approach is based on the development of a hazard function [lambda](t,z) = exp(z[beta])[[lambda].

If X denotes the life time of a component or of living organism, then the past entropy of X is defined as [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] (4) where F(t) is the cumulative distribution function and [tau](t) = f(t)/F(t) is the reversed hazard function or reversed failure rate of X.

The risk or hazard function represents the instant probability of change; it means the duration between the active stage and its ending.

95 Hardcover TA169 Rai (business statistics, Wayne State University) and Singh (Rapid Global Business Solutions) present methods for arriving at hazard rate estimates when mileage accumulation rates in the vehicle population are available in the case of hard failures, estimating hazard function when mileage accumulation rate is not available, and addressing bias in warranty data due to customer-rush near the warranty expiration limit.

There are expanded discussions on the relevant subjects of epistemic uncertainties, crossover designs, equivalence trials and studies, hazard functions, and the log-rank test.
