coxph reference hazard rate
...ng variable is TRUE. For example, when the bucket is ks008 and fidelity <= 3, then the rate, compared to the base rate h_0(t), is h(t) = 0.200 h_0(t). My question is then, to what case does the base hazard rate correspond to? I would expect the reference to be the first factor value, i.e. bucket jpc001 with fidelity <= 3, but its exp(coef) is not one. I verified the contrasts, and the row corresponding to the first factor value is zero everywhere; moreover, I didn't change the default, so a bad setting of the contrasts doesn't seem to be the issue. Best, ge Call: coxph(formula = Sur...
