get_elts_loglog: The R implementation to get the elements necessary for calculations for the log-log setting (a=0, b=0).

Description

The R implementation to get the elements necessary for calculations for the log-log setting (a=0, b=0).

Usage

get_elts_loglog(
  hdx,
  hpdx,
  x,
  setting,
  centered = TRUE,
  profiled_if_noncenter = TRUE,
  scale = "",
  diagonal_multiplier = 1
)

Value

A list that contains the elements necessary for estimation.

n

The sample size.

p

The dimension.

centered

The centered setting or not. Same as input.

scale

The scaling method. Same as input.

diagonal_multiplier

The diagonal multiplier. Same as input.

diagonals_with_multiplier

A vector that contains the diagonal entries of \(\boldsymbol{\Gamma}\) after applying the multiplier.

setting

The same setting as in the function argument.

g_K

The \(\boldsymbol{g}\) vector. In the non-profiled non-centered setting, this is the \(\boldsymbol{g}\) sub-vector corresponding to \(\mathbf{K}\).

Gamma_K

The \(\boldsymbol{\Gamma}\) matrix with no diagonal multiplier. In the non-profiled non-centered setting, this is the \(\boldsymbol{\Gamma}\) sub-matrix corresponding to \(\mathbf{K}\).

g_eta

Returned in the non-profiled non-centered setting. The \(\boldsymbol{g}\) sub-vector corresponding to \(\boldsymbol{\eta}\).

Gamma_K_eta

Returned in the non-profiled non-centered setting. The \(\boldsymbol{\Gamma}\) sub-matrix corresponding to interaction between \(\mathbf{K}\) and \(\boldsymbol{\eta}\).

Gamma_eta

Returned in the non-profiled non-centered setting. The \(\boldsymbol{\Gamma}\) sub-matrix corresponding to \(\boldsymbol{\eta}\).

t1,t2

Returned in the profiled non-centered setting, where the \(\boldsymbol{\eta}\) estimate can be retrieved from \(\boldsymbol{t_1}-\boldsymbol{t_2}\hat{\mathbf{K}}\) after appropriate resizing.

Arguments

hdx

A matrix, \(h(\mathbf{x})\) applied to the distance of x from the boundary of the domain, should be of the same dimension as x.

hpdx

A matrix, \(h'(\mathbf{x})\) applied to the distance of x from the boundary of the domain, should be of the same dimension as x.

x

An n by p matrix, the data matrix, where n is the sample size and p the dimension.

setting

A string, log_log.

centered

A boolean, whether in the centered setting (assume \(\boldsymbol{\mu}=\boldsymbol{\eta}=0\)) or not. Default to TRUE.

profiled_if_noncenter

A boolean, whether in the profiled setting (\(\lambda_{\boldsymbol{\eta}}=0\)) if non-centered. Parameter ignored if centered=TRUE. Default to TRUE.

scale

A string indicating the scaling method. Returned without being checked or used in the function body. Default to "norm".

diagonal_multiplier

A number >= 1, the diagonal multiplier.

Examples

n <- 50
p <- 30
eta <- rep(0, p)
K <- diag(p)
domain <- make_domain("uniform", p=p, lefts=c(0), rights=c(1))
x <- gen(n, setting="log_log", abs=FALSE, eta=eta, K=K, domain=domain,
       xinit=NULL, seed=2, burn_in=1000, thinning=100, verbose=FALSE)
h_hp <- get_h_hp("min_pow", 1.5, 3)
h_hp_dx <- h_of_dist(h_hp, x, domain) # h and h' applied to distance from x to boundary
elts <- get_elts_loglog(h_hp_dx$hdx, h_hp_dx$hpdx, x, setting="log_log", centered=TRUE,
       scale="", diag=1.5)
elts <- get_elts_loglog(h_hp_dx$hdx, h_hp_dx$hpdx, x, setting="log_log", centered=FALSE,
       profiled_if_noncenter=TRUE, scale="", diag=1.7)
elts <- get_elts_loglog(h_hp_dx$hdx, h_hp_dx$hpdx, x, setting="log_log", centered=FALSE,
       profiled_if_noncenter=FALSE, scale="", diag=1.9)
