powermcp {MCPAN} | R Documentation |
Approximative power calculation for multiple contrast tests, based on normal approximation.
powermcp(TExpH1, alpha = 0.05, corrmatH1, alternative = "two.sided")
TExpH1 |
numeric vector: the expectation of the test statistics under the alternative |
alpha |
a single numeric value: alpha-level, defaults to 0.05 |
corrmatH1 |
a numeric matrix, the correlation matrix of the teststatistics under the alternative, must have same dimensions as length of TExpH1 |
alternative |
a single character string, specifying the alternative, one of "two.sided", "less", or "greater" |
Any-pair-power is calcualted, the power of a Union-Intersection-Test.
The probability, that any teststatistic exceeds the critical value is calculated from a central multivariate standard normal distribution. The appropriateness of the result strongly depends on the assumptions, that teststatistics are truely following a standard normal distributions, which might not be the case for small sample sizes.
A single numeric value, the approximative power.
