yXn: Prepare design matrix for nested model with groups and subgroups

Description

Prepares design matrix for nested model with groups and subgroups and response vector in corresponding order.

Usage

yXn(response, group, subgroup)

Arguments

response

Response vector as provided (numeric).

group

Vector of group labels as provided (either numeric or character).

subgroup

Vector of subgroup labels as provided (either numeric or character).

Value

Returns a list with following components.

X

A binary matrix with number of rows equal to length of response and number of columns equal to the total number of levels of treatments and blocks plus one. Each row has exactly three 1s: in the first position and in the two positions representing the group and the subgroup.

y

Numeric vector of response values, permuted to correspond with the rows of X.
