- u
- Indicates survival for each of the 10 years.
- w
- Counts offspring for each of the 10 years.
- v
- Indicates if
`w > 0`

for each of the 10 years. - z
- A covariate of potential interest, 10 in total.
- variables
- Character vector giving the names of the variables in the graph.
- root
- The root data. For

an`nind`

matrix, for`aster.formula`

an`nind * nnode`

vector. - modmat
- An
`nind`

by`nnode`

by`ncoef`

three-dimensional array, the model matrix.`aster.formula`

constructs such a modmat from its formula, the data frame data, and the variables in the environment of the formula. - formula

`asterdata`

corresponding to the
original data set, and vectors specifying the graphical
structure of the aster model. There are 3000 simulated individuals in this aster analysis.
Our data is generated in two parts. The first part follows
Technical report 671 (TR 671) on Charlie Geyer's Aster
Models for Life History Analysis webpage. For our data,
`nind = 3000`

, `ntime = 10`

, `psurv = 0.95`

, `prepr = 0.7`

, `mpois = 1`

,
and the seed is set at `set.seed(13)`

which is different
from the original simulation setup.

We follow the model construction in TR 671 through `out6`

.
We then generate a new dataset from the aster model where
the components of the submodel mean-value parameter vector
$\tau$ corresponding to Darwinian fitness is in the
space spanned by the first, second, and fourth eigenvectors
of Fisher information.
