The function prof_mean_var_Delta computes the profile extrema functions for the mean and variance functions of the difference process \(Z_x - \widetilde{Z}_x\) at x.
prof_mean_var_Delta(kmModel, simupoints, allPsi = NULL,
options_full_sims = NULL, options_approx = NULL, F.mat = NULL,
T.mat = NULL)the km model of the Gaussian process \(Z\).
the matrix \(l x d\) containing the pilot points \(G\).
optional list of matrices (dim \(pxd\)) for which to compute the profile extrema. If NULL coordinate profiles are computed.
an optional list of options for getAllMaxMin(or approxProfileExtrema if allPsi not NULL). If NULL the full computations are not excuted. NOTE: this computations might be very expensive!
an optional list of options for approxMaxMin (or approxProfileExtrema if allPsi not NULL).
the evaluation of the trend function at rbind(kmModel@X,simupoints), see model.matrix, if NULL it is computed.
the upper triangular factor of the Choleski decomposition of the covariance matrix of rbind(kmModel@X,simupoints), if NULL it is computed.
the profile extrema functions at options_approx$design for the mean and variance function of the difference process \(Z^\Delta = Z_x - \widetilde{Z}_x\).
