power.binom | R Documentation |
Calculates power for the generic binomial test with (optional) Type 1 and Type 2 error plots.
power.binom.test(size, prob, null.prob = 0.5, alpha = 0.05,
alternative = c("two.sided", "one.sided", "two.one.sided"),
plot = TRUE, verbose = TRUE, pretty = FALSE)
size |
number of trials (zero or more). |
prob |
probability of success on each trial under alternative. |
null.prob |
probability of success on each trial under null. |
alpha |
type 1 error rate, defined as the probability of incorrectly rejecting a true null hypothesis, denoted as |
alternative |
direction or type of the hypothesis test: "two.sided", "one.sided", or "two.one.sided". For non-inferiority or superiority tests, add or subtract the margin from the null hypothesis value and use alternative = "one.sided". |
plot |
logical; |
verbose |
logical; whether the output should be printed on the console. |
pretty |
logical; whether the output should show Unicode characters (if encoding allows for it). |
size |
number of trials (zero or more). |
prob |
probability of success on each trial under alternative. |
null.prob |
probability of success on each trial under null. |
binom.alpha |
critical value(s). |
power |
statistical power |
# one-sided
power.binom.test(size = 200, prob = 0.6, null.prob = 0.5,
alpha = 0.05, alternative = "one.sided")
# two-sided
power.binom.test(size = 200, prob = 0.4, null.prob = 0.5,
alpha = 0.05, alternative = "two.sided")
# equivalence
power.binom.test(size = 200, prob = 0.5, null.prob = c(0.4, 0.6),
alpha = 0.05, alternative = "two.one.sided")
