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.
