DunnettTests: Software implementation of step-down and step-up Dunnett test procedures. For the implementation of the step-down or step-up Dunnett testing procedures, the package includes R functions to calculate critical constants and R functions to calculate adjusted P-values of the test . 2 DunnettTests-package DunnettTests-package R implementation of step-down and step-up Dunnett test procedures Description For the implementation of the step-down or step-up Dunnett test procedures, the package includes R functions to calculate critical constants and R functions to calculate adjusted P-values of test statistics. DunnettTest does the post hoc pairwise multiple comparisons procedure. If x is a list, its elements are taken as the samples to be compared, and hence have to be numeric data vectors. In this case, g is ignored, and one can simply use DunnettTest(x) to perform the test.

Best, Stephan. filesnowfirstbestsearchfilms.info html. Details. A many-to-one comparison test for the the null hypothesis that all the treatment effects are equal to zero against the alternative that at least one is larger. DunnettTest does the post hoc pairwise multiple comparisons procedure. If x is a list, its elements are taken as the samples to be compared, and hence have to be numeric data vectors. In this case, g is ignored, and one can simply use DunnettTest(x) to perform the test. Bartlett’s test and Levene’s test can be used to check the homoscedasticity of groups from a one-way anova. A significant result for these tests (p test function in the native stats package. For the implementation of the step-down or step-up Dunnett testing procedures, the package includes R functions to calculate critical constants and R functions to calculate adjusted P-values of the test statistics. In addition, the package also contains functions to evaluate testing powers and hence the necessary sample sizes specially for the classical problem of comparisons of several.

A multiple comparison procedure for comparing. $\begingroup$ Thanks very much for your answer. I think you are right about not thinking of how many stars are there - people should be looking at the P-value anyway. I think I will have to set the seed to a known value though, because in order to validate my program the resuls must be reproducible exactly.
