Estimability Check

Description

Checks the estimability of row vectors of coefficients.

Usage

  estmb(L, X, g2, eps=1e-8)

Arguments

L

row vectors of coefficients

X

a model (design) matrix from ModelMatrix

g2

g2 generalized inverse of crossprod(X)

eps

An absolute value less than this is considered to be zero.

Details

It checks the estimability of L, row vectors of coefficients. This corresponds to the ESTIMATE statement of SAS PROC GLM. See <Kennedy Jr. WJ, Gentle JE. Statistical Computing. 1980> p361 or <Golub GH, Styan GP. Numerical Computations for Univariate Linear Models. 1971>.

Value

a vector of logical values indicating which rows are estimable (as TRUE)
