Dear Statalisters,

According to stata manual the command -stcox- estimates the following model:

h(t) = h0(t) exp(b1x1 +... + bkxk)

where h(t) is the hazard to survival.

Can I infer from this specification that bk in its original form
(nohr) measures the percent change of the hazard to survive with
respect to xk?
