Hierarchical model matrix

Create list with information including a model matrix, associated with the geo_unit_data and hierarchical_levels

Usage

hierarchical_model_matrix(geo_unit_index_data, hierarchical_level)

Arguments

geo_unit_index_data

tibble with unique hierarchical levels (one column for each level, one row per combi)

hierarchical_level

vector with hierarchical spec from highest to lowest levels

Value

A list with components modelmatrix, assign, and index:

• modelmatrix: A matrix where each column refers to one eta (number of rows equals number of lowest level units).

• assign: Integer vector of length equal to the number of etas; 0 for the intercept, then a hierarchical level index (starting at 2) for each eta level.

• index: A tibble with n_eta rows, and columns:

  • i: Index of eta

  • column: Hierarchical level

  • level: Name of hierarchical level

All components are associated with the provided geo_unit_data and hierarchical_levels.
