Performs Rao's spacing test of uniformity.
1 2 3 | rao.spacing.test(x, alpha=0)
## S3 method for class 'rao.spacing.test'
print(x, digits = 4, ...)
|
x |
a vector. The object is coerced to class
|
alpha |
numeric value specifying the significance level of the test. The default value is 0, in which case, a range for the p-value will be returned. Valid significance levels are 0.10, 0.05, 0.01 and 0.001. |
digits |
integer indicating the precision to be used. |
... |
further arguments passed to or from other methods. |
If alpha is specified, critical values are determined (using the print
function) from a table of simulated critical points (see reference below); in this case the print
function return a further value accepted
which is TRUE
if the null hypothesis is accepted and FALSE
otherwise. If alpha is not specified, a range for the p-value is determined using the table of simulated critical points in the print
function but not reported.
a list with the statistic, alpha and the number of observations.
