Hello R-sig-Geo subscribers,
I would like to know if there is an easy way to test the statistical
significance of temporal K function (ideally using the results from splancs
stkhat function). I assume this is an easy problem. There seems to be many
textbooks and websites explaining spatial K function, while not so many
about temporal K function.
I really appreciate if anybody can tell me ways to test the significance of
temporal K function (with R codes), as well as guides to interpret the
results..
Space-time K-functionslibrary(splancs)
Space-time K-functionsdata(burkitt)
bur1 <- stkhat(burpts, burkitt$t, burbdy, c(400, 5800), seq(1,40,2),
seq(100, 1500, 100))
oldpar <- par(mfrow=c(2,1))
plot(bur1$s, bur1$ks, type="l", xlab="distance", ylab="Estimated K",
main="spatial K function")
plot(bur1$t, bur1$kt, type="l", xlab="time", ylab="Estimated K",
main="temporal K function")
par(oldpar)
Thanks in advance,
George
