One-Sample Covariance Test by Srivastava, Yanagihara, and Kubokawa (2014)
Description
Given data, it performs 1-sample test for Covariance where the null hypothesis is
H_0 : \Sigma_n = \Sigma_0
where \Sigma_n
is the covariance of data model and \Sigma_0
is a
hypothesized covariance based on a procedure proposed by Srivastava, Yanagihara, and Kubokawa (2014).
Usage
syk(data, Sigma0, alpha)
Arguments
data |
an |
Sigma0 |
a |
alpha |
level of significance. |
Value
a named list containing
- statistic
a test statistic value.
- threshold
rejection criterion to be compared against test statistic.
- reject
a logical;
TRUE
to reject null hypothesis,FALSE
otherwise.
Examples
## generate data from multivariate normal with trivial covariance.
p = 5;n=10
data = matrix(rnorm(n*p), ncol=p)
alpha=0.05
Sigma0=diag(ncol(data))
## run the test
syk(data, Sigma0, alpha)
