oceSurv2WRMW function

Converts Survival Fits to Win Ratio and Mann-Whitney Estimates

oceSurv2WRMW(time0, surv0, time1, surv1)

Arguments

• time0: vector of times for group=0 subset
• surv0: vector of survival distribution values for group=0
• time1: vector of times for group=1 subset
• surv1: vector of survival distribution values for group=1

Returns

A list with the following elements (where Yg=ordered composite endpoint score for group=g):

• int01: estimate of P[Y0>Y1]
• int10: estimate of P[Y1>Y0]
• WR: win ratio, int10/int01
• MW: estimate of P[Y1>Y0]+(1/2)P[Y1=Y0]

WR=WR,MW=MW,int10=int10,int01=int01
