Computes the treatment information matrix

The function cmatbd computes the information matrix (C-matrix) for treatment effects under either the linear fixed effects model or the linear mixed effects model setting for a given block design of size 2.

Keywords
information matrix, C-matrix
Usage
cmatbd(trt.N, blk.N, theta, des)
Arguments
trt.N

integer, specifying number of treatments, v.

blk.N

integer, specifying number of blocks, b.

theta

numeric, representing function of the ratio of random block variance and random error variance. It takes any value between 0 and 1, inclusive.

des

matrix, a 2 x b block design with b blocks of size k = 2 and v treatments.

Value

Returns a v x v treatment information matrix (C-matrix).
