Hazard function

  1. Dec 17, 2004 #1
    Anyone know how to find the hazard function when given the survival function. I am able to calculate the cumulative hazard function, but cannot find a formula for just the hazard function. survival function is:
    S(t)=e^(-at-bt2)

    Or if you don't have them available for, say, a specific distribution, go with numerical approximations.

    The hazard function is:

    [tex]
    h(t)=- \frac{d Ln[S(t)]}{dt}
    [/tex]

    The cumulative hazard function is:

    [tex]
    H(t)=-Ln[S(t)]
    [/tex]
