PRECISION Subcommand (POWER SPEARMAN ONESAMPLE command)

The optional PRECISION subcommand estimates the sample size based on confidence intervals. The subcommand takes effect when POWER is specified and TEST = NONDIRECTIONAL. The keyword is ignored otherwise.

HALFWIDTH = values
The optional keyword specifies the values of the confidence interval half-widths. At least one value must be specified. When multiple values are specified, they are separated by a blank space (or blank spaces). All valid values must be greater than 0 and less than or equal to 1. Duplicate values are ignored.
