Calculate Sample Size Needed to Test 1 Mean: 1-Sample, 1-Sided This calculator is useful for tests concerning whether a mean,μμ, is equal to a reference value,μ0μ0. The Null and Alternative hypotheses is either H0:μ=μ0H0:μ=μ0 ...
In a recent paper Rhmel and Mansmann (1999) discussed p-values for unconditional two-sample binomial tests of the one-sided type. Since uniformly smallest p-values do not exist, they considered undominated or, in their notation, acceptable p-values. Rhmel and Mansmann showed that any p-va...
If the sample size is large, they can be applied with unknown variance and with the binomial data or survival data with random censoring.doi:10.1080/03610929608831742T. Timothy Chen & Richard SimonBiometric Research BranchCommunications in Statistics - Theory and Methods...

Test Relative Incidence in Self Controlled Case Series Studies SCCS, Alt-2 Other 1-Sample Normal 1-Sample Binomial Calculate Sample Size Needed to Compare 2 Means: 2-Sample, 1-Sided This calculator is useful for tests concerning whether the means of two groups are different. Suppose the two...
This calculator is useful for tests concerning whether the proportions in two groups are different. Suppose the two groups are 'A' and 'B', and we collect a sample from both groups -- i.e. we have two samples. We perform a two-sample test to determine whether the proportion in group ...
