Finds the critical value in a one-tailed binomial test
findcr(sample.size, alpha = .05, p0 = .5)
sample.size |
the sample size of the binomial test (must be a positve integer) |
alpha |
the type I error-level of the test (must be between zero and one) |
p0 |
the binomial probability under the null-hypothesis (must be between zero and one); 1/2 for the duotrio and twoAFC tests and 1/3 for the triangle and threeAFC tests |
The critical value in a one-tailed binomial test, that is, the smallest integer such that the null hypothesis binomial probability of being larger than or equal to this number is smaller than or equal to the type I error-level of the test
