size.test.sign.ps | R Documentation |
Computes sample size required for a Sign test with desired power in a paired-samples design. A planning value of the paired-samples Sign test parameter is required. In a paired-samples experiment, this parameter is the proportion of members in the population with scores that would be larger under treatment 1 than treatment 2. In a paired-samples nonexperiment, this parameter is the proportion of members in the population with measurement 1 scores that are larger than their measurement 2 scores.
