Sample size algorithm

2002-04-03 Thread Virgil Stokes
Is there an exact algorithm for calculating the sample size in a paired t-test for the mean difference when: 1) the standard deviation of the population is unknown 2) there is a finite population 3) continuous measurements 4) both alpha and beta (or the power) for the test are specified Any
