Test: checking for Censoring Rates

Fixed design, two-arm trial with time-to-event
outcome (Lachin and Foulkes, 1986).
Solving for:  Accrual duration 
Hazard ratio                  H1/H0=0.6/1
Study duration:                   T=172.197
Accrual duration:                   171.997
Min. end-of-study follow-up: minfup=0.2
Expected events (total, H1):        160.6536
Expected sample size (total):       171.997
Accrual rates:
      Stratum 1
0-172         1
Control event rates (H1):
      Stratum 1
0-Inf    0.1155
Censoring rates:
      Stratum 1
0-Inf         0
Power:                 100*(1-beta)=90%
Type I error (1-sided):   100*alpha=2.5%
Equal randomization:          ratio=1
