Usage

rhoPowerExp(u, a, k)

Arguments

u

a value which indicates the distance

a

a value which indicates the scale parameter, $\phi$

k

a value which indicates the shape parameter, $\kappa$

Value

A value of the correlation.

Details

The function is $\; \; \rho (u)=\exp ((-u/\phi)^\kappa) \; \;$. When using the powered exponential correlation function, note that $0
