Build nodes and weights for integration over agent choice probabilities.
This function can be used to build custom
Probleminitialization. Specifically, this function affords more flexibility than passing an
Integrationconfiguration directly to
Problem. For example, if agents have unobserved tastes over only a subset of demand-side nonlinear product characteristics (i.e., if
Problem.solve()has columns of zeros), this function can be used to build agent data with fewer columns of integration nodes than the number of unobserved product characteristics, \(K_2\). This function can also be used to construct nodes that can be transformed into demographic variables.
To build nodes and weights for multiple markets, this function can be called multiple times, once for each market.
integration (Integration) –
Integrationconfiguration for how to build nodes and weights for integration.
dimensions (int) – Number of dimensions over which to integrate, or equivalently, the number of columns of integration nodes. When an
Integrationconfiguration is passed directly to
Problem, this is the number of demand-side nonlinear product characteristics, \(K_2\).
Nodes and weights for integration over agent utilities. Fields:
weights : (numeric) - Integration weights, \(w\).
nodes : (numeric) - Unobserved agent characteristics called integration nodes, \(\nu\).
