signtest_pvalue function

p-value for a one sample sign test

p-value for a one sample sign test based on the binomial distribution.

signtest_pvalue(x, alternative = "two.sided", theta0 = 0, ...)

Arguments

• x: number vector.
• alternative: type of alternative hypothesis
• theta0: null value of the parameter
• ...: optional arguments. currently ignored.

Details

Returns p-value using the binomial distribution.

Returns

a numeric scalar --- the p-value --- is returned

Examples

x <- round(rt(19,9) + 2,1)
signtest_pvalue(x,alternative='greater')
S <- sum(x > 0)
M <- sum(x != 0)
1-pbinom(S-1,M,0.5)
x <- round(rt(19,9) + 0,1)
signtest_pvalue(x)
S <- sum(x > 0)
M <- sum(x != 0)
2*min(pbinom(S,M,0.5), 1-pbinom(S-1,M,0.5))
