Interesting Distributions

  • Weibull
    • proportional hazards property
    • accelerated failure time property
    • hazard can be increasing, decreasing, or flat
  • LogLogistic
    • accelerated failure time property
    • hazard can be increasing, decreasing, flat, or unimodal.
  • LogNormal
    • accelerated failure time property

Regression Models

  • Proportional hazards model
    • $h(t) = c \cdot h_0(t)$
  • Accelerated failure time model
    • $S(t) = S_0(t / \phi)$
