NHANES.dat: Combined NHANES dataset from 1999-2004 NHANES study

In mvnimpute: Simultaneously Impute the Missing and Censored Values

Combined NHANES dataset from 1999-2004 NHANES study

Description

A dataset including the age, gender and diastolic blood pressure, body mass index and 24 PCB measurements.

Usage

NHANES.dat

Format

A list including data frame with 5874 rows and 24 variables and associated indicator matrix:

BPXDAR

Diastolic blood pressure

RIAGENDR

Gender, 1 = male, 2 = female

RIDAGEYR

Age in years

BMXBMI

Body mass index

Details

The dataset is combined from the NHANES release cycles 1999-2000, 2001-2002, and 2003-2004. Almost all PCB have both the missing and censored values as falling below the limits of detection (LODs). The dataset include two components, the first component is the observed NHANES data where the censored PCB measurements are replaced by the LODs dividing the square root of 2. The second component is a data frame including the censoring indicators of the data, in that data frame, 0 indicates an observed PCB measurement, 1 indicates a censored PCB measurement, and 'NA' indicates a missing PCB measurement.

Note

The subset provided here was selected to demonstrate the functionality of the mvnimpute package, no clinical conclusions should be derived from it.
