LS2Wstat (version 2.1-5)

getpval: Computes a p-value for the output of the test for stationarity.

Description

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

Usage

getpval(statvec, verbose = TRUE)

Value

p

The p-value of the test.

Arguments

statvec

#Generate a stationary image

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

# Run test of stationarity

if (FALSE) TestofStat<-TOS2D(testimage)

# Obtain p-value
