od_print {OptimalDesign}

Compact information about a design

Description

Prints various characteristics of an experimental design

Usage

od_print(Fx, w, X=NULL, h=NULL, echo=TRUE)

Arguments

Fx

the n times m (where m>=2, m<=n) matrix containing all candidate regressors (as rows), i.e., n is the number of candidate design points, and m is the number of parameters

w

the vector of non-negative real numbers of length n representing the design

X

an n times k matrix of coordinates of design points

h

a non-zero vector of length m corresponding to the coefficients of the linear parameter combination of interest. If crit is not "C" then h is ignored. If crit is "C" and h=NULL then h is assumed to be c(0,...,0,1)

echo

Print the call of the function?

Value

Output is a list with components

call

the call of the function

design

a matrix with the rows of Fx corresponding to non-zero design weights and the non-weights themselves

M

the information matrix of w

eigenvalues

the eigenvalues of M

D.value

the value of the D-optimality criterion for w

A.value

the value of the A-optimality criterion for w

I.value

the value of the I-optimality criterion for w

C.value

the value of the C-optimality criterion for w

c.value

the value of the c-optimality criterion for w
