Fits the ACTF (Autocorrelation Transformation Function) to the estimated points (\rho_x, \rho_z
) using nls

logical - is the marginal distribution discrete? |
library(CoSMoS)
## choose the marginal distribution as Pareto type II
## with corresponding parameters
dist <- 'paretoII'
distarg <- list(scale = 1, shape = .3)
## estimate rho 'x' and 'z' points using ACTI
p <- actpnts(margdist = dist, margarg = distarg, p0 = 0)
## fit ACTF
fit <- fitactf(p)
## plot the result
plot(fit)
