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 |
