Estimates the first stage of a sorting model
first_stage(code_name, Z_names, X_names, data, print_detail = 3)
| code_name | Indicates (with name or column number) the vector with alternative chosen |
|---|---|
| Z_names | Indicates (with names or column numbers) the vectors with individual data |
| X_names | Indicates (with names or column numbers) the vectors with alternative data |
| data | Dataset to be used |
| print_detail | Controls the output detail of maxLik (default is set at 3) |
A (maxLik) object with the estimates (maxLik) together with the indicators of the alternative chosen, the vectors with individual data, the vectors with city/regional data and the name of the reference alternative
Optimization occurs via the maxLik package for an obtimization of a conditional logit model
