compensateAlpha
compensates statistical significance level
(alpha
) for multiple comparisons/tests.
compensateAlpha(alpha,
n, method = c("bonferroni",
"sidak"), r = 0)
alpha |
significance level to be compensated |
n |
comparison count |
method |
compensation |
r |
optional mean "correlation between the tests made", the extreme value of 0 leads to full compensation, the extreme value of 1 leads to no compensation (as all the tests are considered equal). See the SISA help for explanation. |
Compensated significance level. It equals alpha/n
for the
'bonferroni'
method
, and 1-(1-alpha)^(1/n))
for the 'sidak'
method
.
