...ate the power of the logrank test for different values of rho .I was just wandering whether the following programme would do it. any suggestions are welcome s=50 number=1 count1=0;count2=0;count3=0;count4=0;count5=0;count6=0;count7=0;count7=0; count8=0;count9=0 while(s!=0){ n=20 n1=n/2 n2=n/4 a11=1 ;a12=1.4 ;a21=16 ;a22=a12 * a21 t1<-array(1,c(n1)) t2<-array(2,c(n1)) treatgrp=matrix(c(t1,t2))...

my program given below can some one make it presentable. I trying to simulate survival data and calculate the power. I think i could have done better. s=10 number=0 count1=0;count2=0;count3=0;count4=0;count5=0;count6=0;count7=0;count8=0; count9=0; count11=0;count22=0;count33=0;count44=0;count55=0;count66=0;count77=0; count88=0;count99=0; while(s!=0){ n=100 n1=n/2 n2=n/4 t1<-array(1,c(n1)) t2<-array(2,c(n1)) treatgrp=matrix(c(t1,t2)) st1...

...he loop could either terminate or // loop infinitely, but in either case, the loop is guaranteed to // iterate at least until the iteration where the wrapping occurs. I have no doubt that there is a good reason for this code to work this way (there is a specific check in trip-count9.ll). I'm just trying to understand it better. I'm assuming that when the previous version of this code checked the NoWrap flag, that it caused a problem with some optimization pass? If so, does anyone recall the pass. I'm also curious if the -f[no]-strict-overflow flag has any im...
