      (Non-)Proportional Hazards As we’ve said from the outset, the exponential, Weibull, and Cox models are all proportional hazards (PH) models. That is, • They assume that the effect of a covariate is to shift the hazard proportionally to the baseline. • So, for two individuals A and B, their relative hazards will be: h A(t) = Ch B(t)

      In general, what is always proportional on a linear function is the change in y to the change in x, also known as the line’s slope. This gives rise to what is known as the slope-intercept form of a line. Exercise #2: Given the linear function 1 1 2 gx x do the following. Exercise #3: Use information about the slope and y-intercept to
