The SAS System 13:47 Monday, August 11, 2003 1 WARNING 2: B = 1, so that all tests coincide (univariate case). Since COLLAPSE = 1, power is given as one value with the heading POWER. To print powers with a heading for each test, specify OPT_OFF = {COLLAPSE}. WARNING 10: SIGMA is a scalar. For this program, a scalar SIGMA must equal the variance, NOT the standard deviation. POWER CALCULATION WARNING 22: Power values were rounded to 1 using the value contained in ROUND and should not be be reported as Power = 1. For example, if ROUND = 3 then report Power > 0.999 . This occurred 32 time(s). The results have been stored in SAS file WORK.PWRDT1
