In nunesmatt/LS2Wstat: A Multiscale Test of Spatial Stationarity for LS2W Processes

Description

Computes and returns a p-value from the output of the bootstrap test for stationarity.

Usage

getpval(statvec, verbose = TRUE)

Arguments

statvec

A vector of test statistics, such as that given by TOS2D. The first value must be the value of the test statistic for the original image.

verbose

If TRUE then the p-value is printed and a sentance declaring "stationary" or "not stationary" is printed.

Value

p	The p-value of the test.

Examples

#Generate a stationary image

testimage <- matrix(rnorm(64*64), nrow=64, ncol=64)

# Run test of stationarity

## Not run: TestofStat<-TOS2D(testimage)

# Obtain p-value

getpval(TestofStat$samples)

## End(Not run)
