get_r_uz_bounds {ivdoctr}

Evaluates r_uz bounds given user restrictions on r_TstarU and kappa

Description

This function takes observables from the data and user beliefs over the extent of measurement error (kappa) and the direction of endogeneity (r_TstarU) to generate the implied bounds on instrument validity (r_uz)

Usage

get_r_uz_bounds(r_TstarU_lower, r_TstarU_upper, k_lower, k_upper, obs)

Arguments

r_TstarU_lower

Vector of lower bounds of endogeneity

r_TstarU_upper

Vector of upper bounds of endogeneity

k_lower

Vector of lower bounds on measurement error

k_upper

Vector of upper bounds on measurement error

obs

Observables generated by get_observables

Value

2-column data frame of lower and upper bounds of r_uz
