Example (POWER PROPORTIONS RELATED command)

POWER PROPORTIONS RELATED 
  /PARAMETERS TEST=NONDIRECTIONAL SIGNIFICANCE=0.05 NPAIRS=2 
      VALUES=PROPORTIONS(.5 .75) MARGINAL=TRUE CORRELATION=0 ESTIMATE=NORMAL 
  /PLOT RISK_DIFF DISCORDANT VROTATE(10) HROTATE(325).
  • PARAMETERS specifies that the test direction is non-directional, the significance level uses the default 0.05 value, the total number of pairs is set to 2, the testing values for proportions are set the 0.5 and 0.75, marginal test values are enabled, the correlation between matched pairs is set to 0, and the estimation method is normal approximation.
  • PLOT specifies that the two-dimensional Power estimation versus risk difference chart will display in the output. The three-dimensional Power estimation versus discordant proportions chart will also display in the output. The vertical and horizontal rotation settings use their default values (10 degrees and 325 degrees respectively).
