oceCoxph function

Estimate win ratio or Mann-Whitney parameter using Cox Proportional Hazards

Usually called from within oceTest, but useful for getting coxph output details or customizing graphics. Estimation done using coxph (partial likelihood methods).

oceCoxph(oceData)

Arguments

• oceData: output from oceFormat

Returns

An oceCoxph object, which is a list with the following elements (where Yg=ordered composite endpoint score for group=g):

• oceNames: long names for each of the ordered endpoints
• TAU: maximum of all the time-to-event variables (even censored ones)
• coxOutput: output from coxph function
• int01: estimate of P[Y0>Y1]
• int10: estimate of P[Y1>Y0]
• WR: win ratio, estimate of P[Y1>Y0]/P[Y0>Y1]
• MW: desirability of outcome ranking, estimate of P[Y1>Y0]+(1/2)P[Y1=Y0]
