metric-1D_vs {asreml}R Documentation

Metric-based variance models in one dimension.

Description

Metric-based variance structures in one dimension. Includes one-dimensional exponential, gaussian and linear variance power models (exp, gau, lvr).

Usage

exp(x, init = NA, dist = NA)

expv(x, init = NA, dist = NA)

exph(x, init = NA, dist = NA)

gau(x, init = NA, dist = NA)

gauv(x, init = NA, dist = NA)

gauh(x, init = NA, dist = NA)

lvr(x, init = NA, dist = NA)

lvrv(x, init = NA, dist = NA)

lvrh(x, init = NA, dist = NA)

Arguments

x

An object in data.

init

An optional vector of initial values (power parameters followed by variance parameters) with an optional names attribute from the set {P, U, F} specifying the boundary constraint as positive, unconstrained or fixed, respectively.

dist

Optional numeric vector of coordinates (distances). If missing then the distances are obtained as unique(obj).
