Climate Change with Proxies

Description

This program implements and improves upon the Wilkinson and Ivany approach to climate time series modeling. The jackknife is used to estimate the 95 percent confidence bounds for the modeled estimates. dx should be chosen to be approximately half a cycle or more.

Examples

## Not run: 
data(CLAM1)
x = CLAM1$x
y = CLAM1$y

dx = 3.392

gout = proxyJK(x, y, dx)

plotproxy1(x, y, gout)

par(mfrow=c(2,1))

plotproxy.error(x, y, gout, type = 1)
plotproxy.error(x, y, gout, type = 2)


par(mfrow=c(2,1))
plotproxy.error(x, y, gout, type = 2)

plotproxy.all2(gout,YAXstyle=1 )
