valorate.risk {valorate} | R Documentation |
Estimates the risk (hazard ratio), and confidence interval of a 'mutated' group.
valorate.risk(vro, clusters)
vro |
the valorate object. |
clusters |
a numerical or logical vector representing the two survival groups encoded in 1/TRUE for those 'mutated' (in the group of interest) or 1/FALSE for those who not. Basically this value is the 'x' vector in the VALORATE re-formulation. See references. |
A coxph model depending on clusters is run to establish the risk/hazard ratio.
A number representing the relative risk. The confidence interval, p-value, and the coxph model are included as attributes.
