Overview (POWER SPEARMAN ONESAMPLE command)
POWER SPEARMAN ONESAMPLE invokes the power analysis for the one-sample Spearman
rank-order correlation test.
Options
- Test Assumptions
- Specifies the keywords that control the test assumptions. The keywords specify the sample size, power for sample size estimation, asymptotic variance, null hypothesis value of the correlation parameter, alternative hypothesis value of the correlation parameter, test direction, and the significance level of the type I error rate. For more information, see PARAMETERS Subcommand (POWER SPEARMAN ONESAMPLE command).
- Two-Dimensional Plot
- Controls the two-dimensional power estimation by charts.
- Three-Dimensional Plot
- Controls the three-dimensional power estimation by charts. 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 SPEARMAN ONESAMPLE command and a PARAMETERS subcommand that specifies valid values for the keywords ALTERNATIVE and either POWER or N.
Subcommand order
The subcommands can be named in any order.
