proptest_data

Description

Creates data for a Binomial test based on the properties for the test.

Usage

proptest_data(
  size = 10:100,
  prob = seq(0.05, 0.45, by = 0.05),
  reject = TRUE,
  alternative = c("two.sided", "less", "greater"),
  alpha = c(0.01, 0.05, 0.1),
  norm.approx = NA,
  maxit = 1000
)

Arguments

size	numeric: vector of sample sizes (default 10:100)
prob	numeric: vector of probabilities for the hypothetical proportion \pi_0 (default =seq(0.05, 0.45, by=0.05))
reject	logical: should x generated lead to a rejection of the null hypothesis (default TRUE), if equals NA then this will be igenored
alternative	character: a character string specifying the alternative hypothesis, must be one of two.sided (default), greater or less
alpha	numeric: vector of significance levels (default c(0.01, 0.05, 0.1))
norm.approx	logical: should a normal approximation possible (size*prob*(1-prob)>9)
maxit	integer: maximal numbers of trials to find a solution (default 1000)

Value

a list with the components:

• pi0 hypothetical proportion,

• x counts of successes in the sample,

• n sample size,

• alpha significance level, and

• alternative specifying the alternative hypothesis (either two.sided, greater or less).
