  resample = FALSE
)

Arguments

y_name

Character string with the column name of the dependent variable

T_name

Character string with the column name of the endogenous regressor(s)

z_name

Character string with the column name of the instrument(s)

data

Data frame

example_name

Character string naming estimation

controls

Vector of character strings specifying the exogenous variables

robust

Indicator for heteroskedasticity-robust standard errors

r_TstarU_restriction

2-element vector of min and max of r_TstarU.

k_restriction

2-element vector of min and max of kappa.

n_draws

Number of draws when generating frequentist-friendly draws of the covariance matrix

n_RF_draws

Number of reduced-form draws

n_IS_draws

Number of draws on the identified set

resample

Indicator of whether or not to resample using magnification factor

Value

List with elements:

• ols: lm object of OLS estimation,

• iv: ivreg object of the IV estimation

• n: Number of observations

• b_OLS: OLS point estimate

• se_OLS: OLS standard errors

• b_IV: IV point estimate

• se_IV: IV standard errors

• k_lower: lower bound of kappa

• p_empty: fraction of parameter draws that yield an empty identified set

• p_valid: fraction of parameter draws compatible with a valid instrument

• r_uz_full_interval: 90% posterior credible interval for fully identified set of rho

• beta_full_interval: 90% posterior credible interval for fully identified set of beta

• r_uz_median: posterior median for partially identified rho

• r_uz_partial_interval: 90% posterior credible interval for partially identified set of rho under a conditionally uniform reference prior

• beta_median: posterior median for partially identified beta

• beta_partial_interval: 90% posterior credible interval for partially identified set of beta under a conditionally uniform reference prior

• a0: If treatment is binary, mis-classification probability of no-treatment case. NULL otherwise

• a1: If treatment is binary, mis-classification probability of treatment case. NULL otherwise

• psi_lower: lower bound for psi

• binary: logical indicating if treatment is binary

• k_restriction: User-specified bounds on kappa

• r_TstarU_restriction: User-specified bounds on r_TstarU
