logL.GP {COST}

negtive log-likelihood of Gaussian process

Description

negtive log-likelihood of Gaussian process, with mean vector and variance vector obtained by the empirical version, and it is for parameter estimation in the correlation matrix

Usage

logL.GP(par,Y,s.ob)

Arguments

par

parameters in the copula function, will be obtained by minimizing the negtive log-likelihood

Y

the data set from observed locations, used for parameter estimation

s.ob

coordinates of observed locations

Value

the negative log-likelihood
