Description Usage Arguments Details Value Author(s) See Also Examples
This function calculates the Matern correlation.
1 | rhoMatern(u, a, k)
|
u |
a value which indicates the distance |
a |
a value which indicates the scale parameter, φ |
k |
a value which indicates the shape parameter, κ |
The function is \; \;ρ (u)= [2^{κ-1}τ(κ)]^{-1} (-u/φ)^κ K_κ(-u/φ) \; \; where K_κ(\cdot) denotes a modified Bessel function of order κ.
A value of the correlation.
