Runs test for randomness
runs.test(y, plot.it = FALSE, alternative = c("two.sided", "positive.correlated", "negative.correlated"))
| y | A vector |
|---|---|
| plot.it | A logical. whether or not draw a plot |
| alternative | a character string specifying the alternative hypothesis, must be one of "two.sided" (default), "greater" or "less". |
A list with class "htest" containing the following components: statistic,p-value,method and data.name
