We derive an explicit form for power/sample size calculation based on these two tests. A number of simulation studies have been used to illustrate the efficiency of the tests for the case-cohort design. An example is provided on how to use the formula. 展开 关键词:...
Statistical power analysis provides a method of determining the sample sizes needed to control for errors in hypothesis testing. Power is largest when the effects being studied are large and the sample is large. Keywords: power; standard error; effect size; noncentral F ; analysis of variance...
Power and Sample Size Calculation Using SAS Menu Power and sample size can also be calculated using the menu in SAS. When using the menu, the user should specify the chosen design for the underlying project, and then fill in the required parameters needed to do the calculation for each desig...
