omega_all¶

All Node omega Values¶

The combination of the omega_all and omega_index tables specify the value of omega for all the nodes that have omega data.

omega_all Table¶

This table specifies the value of omega for each age, time point in the omega_grid, every node, and each reference in the split_reference_table. This data is used to compute the omega_constraint for each node. If omega is not specified for a node, it will use the same omega values as its nearest ancestor node. It is an error if there is no ancestor of a goal node that has omega data.

omega_all_id¶

is the Primary Key for this table.

omega_all_value¶

This column has type real and is the value of omega for a specific node, age, and time; see omega_index table below. Each value in this column is omega at a specific age and time not on an age or time interval. If you only have omega on age and time intervals, use the midpoint age and midpoint time in the omega grid.

omega_index Table¶

This table specifies the omega_all_id at which the omega values for a particular node and split_reference begin. Specifications for which age and time points correspond to each omega_all_id are included below.

omega_index_id¶

is the Primary Key for this table.

node_id¶

This column has type integer and specifies a node by its index in the root node database node table.

split_reference_id¶

This column has type integer and it specifies the index of a value in split_reference_table. If split_reference_table is empty (is not empty), the values in this column must be (must not be) null.

omega_all_id¶

This column has type integer and specifies the index in the omega_all table where the omega values begin, for this node and split_reference value. For the age index i equal 0 through n_omega_age-1 and time index j equal 0 through n_omega_time-1

omega_all_id + i * n_omega_time + j

is the value of omega_all_id in the omega_all table where the omega_all_value is located for this node_id, this split_reference_id, the i-th age in the omega_grid, and the j-th time in the omega_grid. Note that each omega_all_id in the omega_index table should be a multiple of n_omega_age * n_omega_time (because there are that many omega entries for each node and each split_reference value).
