Overview (POWER PROPORTIONS INDEPENDENT command)
POWER PROPORTIONS INDEPENDENT invokes power analysis for the independent-sample
binomial test.
Options
- Test Assumptions
- Specifies the keywords that control the test assumptions. The keywords specify the sample size, total number of trials for groups, proportion parameters for groups, significance level, tests, estimation method, and test direction. For more information, see PARAMETERS Subcommand (POWER PROPORTIONS INDEPENDENT command).
- Two-Dimensional Plot
- Controls the two-dimensional power estimation by charts.
- Three-Dimensional Plot
- Controls the three-dimensional power estimation by sample chart, and the three-dimensional power by null hypothesis value chart. Also controls the vertical rotation degrees (clockwise from the left) and the horizontal rotation degrees (clockwise from the front) for the three-dimensional chart.
- Precision
- Estimates the sample size based on confidence intervals by specifying the values of the confidence interval half-widths.
Basic specification
The basic specification is the POWER PROPORTIONS INDEPENDENT command and a PARAMETERS subcommand that specifies valid values for the keywords PROPORTIONS and either POWER or N.
Subcommand order
The subcommands can be named in any order.
