BMI {swgee}

BMI dataset

Description

a subset of the the Framingham Heart Study Data. The data set consists of measurements of 100 patients from a series of exams with 5 assessments for each individual. Individual's obesity status, age, systolic blood pressure (SBP) and cholesterol level (CHOL) are collected at each assessment.

Usage

data("BMI")

Format

A data frame with 500 observations on the following 7 variables.

id

a numeric vector for subject id

visit

a numeric vector for assessment time

age

a numeric vector of age

sbp

a numeric vector of systolic blood pressure

chol

a numeric vector of cholesterol level

bbmi

an indicator of obesity status(1=yes, 0=no)

O

an indicator of observed measurement(1=yes, 0=no)
