| SpearmanTest {coin} | R Documentation |
Testing the independence of two numeric variables.
## S3 method for class 'formula':
spearman_test(formula, data, subset = NULL, weights = NULL, ...)
## S3 method for class 'IndependenceProblem':
spearman_test(object,
distribution = c("asymptotic", "approximate"), ...)
formula |
a formula of the form y ~ x | block where y
and x are numeric variables and block is an
optional factor for stratification. |
data |
an optional data frame containing the variables in the model formula. |
subset |
an optional vector specifying a subset of observations to be used. |
weights |
an optional formula of the form ~ w defining
integer valued weights for the observations. |
object |
an object of class IndependenceProblem. |
distribution |
a character, the null distribution of the test statistic
can be approximated by its
asymptotic distribution (asymptotic)
or via Monte-Carlo resampling (approximate).
Alternatively, the functions
approximate or asymptotic can be
used to specify how the exact conditional distribution of the test statistic
should be approximated. |
... |
further arguments to be passed to or from methods. |
The null hypothesis of the independence of y and x
is tested.
An object inheriting from class IndependenceTest-class with
methods show, statistic, expectation,
covariance and pvalue. The null distribution
can be inspected by pperm, dperm,
qperm and support methods.
