PLOT Subcommand (POWER PROPORTIONS INDEPENDENT command)

The optional PLOT subcommand controls the output charts. By default, no charts are created. When the subcommand is specified, only the outputs for the following keywords are created.

N1_XAXIS(integer1 integer2) N2_YAXIS(integer1 integer2)

The optional keyword controls the three-dimensional power by number of trials in Group 1 (x -axis) and number of trials in Group 2 (y-axis) chart. The chart is suppressed by default. When the keyword is specified, the chart displays. When no integers are specified, the default plot range is used. Both integer1 and integer2 are integers, separated by a blank space (or blank spaces). You can either omit or specify both integer values.

N1_YAXIS(integer1 integer2) N2_XAXIS(integer1 integer2)

The optional keyword controls the three-dimensional power by number of trials in Group 2 (x -axis) and number of trials in Group 1 (y-axis) chart. The chart is suppressed by default. When the keyword is specified, the chart displays. When no integers are specified, the default plot range is used. Both integer1 and integer2 are integers, separated by a blank space (or blank spaces). You can either omit or specify both integer values.

P1_XAXIS P2_YAXIS

The optional keyword controls the three-dimensional power by proportion of Group 1 (x -axis) and proportion of Group 2 (y-axis) chart. The chart is suppressed by default. When the keyword is specified, the chart displays.

P1_YAXIS P2_XAXIS

The optional keyword controls the three-dimensional power by proportion of Group 2 (x -axis) and proportion of Group 1 (y-axis) chart. The chart is suppressed by default. When the keyword is specified, the chart displays.

NRATIO (value1 value2)

The optional keyword controls the two-dimensional power by group size ratio chart. The chart is suppressed by default. When the keyword is specified, the chart displays. When no values are specified, the default plot range is used. Both value1 and value2 are separated by a blank space (or blank spaces). You can either omit or specify both values.

TOTAL_N

The optional keyword is valid only when a range of POWER values is specified. The keyword is ignored when either a single POWER value is specified or /PARAMETERS specifies N. For each integer N displayed in the TOTAL_N plot, N1 and N2 are defined as N1=N/(1+R), N2=(N*R)/(1+R), where R=NRATIO. Note that for each integer N, N1 and/or N2 may be fractional. N_min and N_max are nevertheless computed from P_min and P_max.

RISK_DIFF

The optional keyword controls the two-dimensional power by risk difference chart. The chart is suppressed by default. When specified, the chart displays.

RISK_RATIO (value1 value2)

The optional keyword controls the two-dimensional power by risk ratio chart. The chart is suppressed by default. When specified, the chart displays. When no values are specified within the parentheses, the default plot range of the risk ratio is used. When specified, the plot boundaries are determined by value1 and value2, respectively. Both value1 and value2 are separated by a blank space (or blank spaces). You can either omit or specify both values.

ODDS_RATIO (value1 value2)

The optional keyword controls the two-dimensional power by odds ratio chart. The chart is suppressed by default. When specified, the chart displays. When no values are specified within the parentheses, the default plot range of the odds ratio is used. When specified, the plot boundaries are determined by value1 and value2, respectively. Both value1 and value2 are separated by a blank space (or blank spaces). You can either omit or specify both values.

VROTATE(integer)

The optional keyword sets the vertical rotation degrees (clockwise from the left) for the three-dimensional chart. The keyword takes effect when the three-dimensional plot is requested. The value must be a single integer ∈[0,359] with 10 as the default setting.

HROTATE(integer)

The optional keyword sets the horizontal rotation degrees (clockwise from the front) for the three-dimensional chart. The keyword takes effect when the three-dimensional plot is requested. The value must be a single integer ∈[0,359] with 325 as the default setting.
