NHANES_blood_lead_small_matched {sensitivityCalibration}

NHANES_blood_lead_small data after matching.

Description

NHANES_blood_lead_small data after a full matching using the optmatch package

Usage

data(NHANES_blood_lead_small_matched)

Format

NHANES_blood_lead_small dataset after a full matching. It consists of 500 instances and the following 12 variables:

COP

treatment, 1 if cotinine level is between 0.563-14.9 ng/ml and 0 otherwise

DMARETHN

1 if white, 0 if others

DMPPIR

Poverty income ratio

HFE1

1 if the house is built before 1974, 0 if after 1974

HFE2

number of rooms in the house

HFHEDUCR

education level of the reference adult

HSAGEIR

age at the time of interview

HSFSIZER

size of the family

HSSEX

1 if male, 0 if female

PBP

blood lead level

U0

placeholder for the hypothesized unmeasured confounder U

matches

matched set assignment

Details

We perform a full matching on the NHANES_blood_lead_small dataset using the optmatch package. The code for constructing this matched dataset from the original dataset is given in the examples section. We add a column U0 as placeholder for the unmeasurefor confounder U.
