The Sign Test
Description
A nonpametric test for center. The sign test compares the median to a value.
Usage
signtest(x, m = NULL, alpha = NULL,
alternative =c("two.sided", "greater", "less"), conf.level=NULL, exact = FALSE)
Arguments
x |
A vector of sample data. |
m |
The median to test. Defaults to 0. |
alpha |
The Significance level, defaults to 0.05. |
alternative |
Defaults to two.sided. Used to determine what type of test to run. |
conf.level |
Defaults to NULL. Used to construct a confidence interval. Input as a decimal. |
exact |
Defaults to FALSE. Used to determine whether to run the exact procedure or a large sample approximation. |
Value
B |
The Test Statistic |
Significance Level |
Returns the alpha value. |
P-value |
Returns the p-value from the Sign Test. |
Confidence Interval |
The confidence interval requested. |

Examples
## Run the Sign Test on the vector.
signtest(c(1.8, 3.3, 5.65, 2.25, 2.5, 3.5, 2.75, 3.25, 3.10, 2.70, 3, 4.75, 3.4), m=3.5)
