Description
kinkyreg: Instrument-free inference for linear regression models with endogenous regressors
kinkyreg implements the kinky least squares estimator for instrument-free inference under confined regressor endogeneity. An arbitrary number of endogenous regressors can be accommodated. Postestimation commands include tests of linear hypotheses and exclusion restrictions, the RESET test, tests for heteroskedasticity, and tests for serial correlation.
