POWER SPEARMAN ONESAMPLE

POWER SPEARMAN ONESAMPLE is available in IBM® SPSS® Statistics Base Edition. The command invokes the power analysis for the one-sample Spearman rank-order correlation test. Spearman rank-order correlation coefficient is a rank-based nonparametric statistic to measure the monotonic relationship between two variables that are usually censored and not normally distributed.
