Regression model
Now it's time for us to build a simple linear regression model for the Weight
of 20-year-olds using Height
. To do so, we first need to subset the design object NHANES_design
to only include 20-year-olds while still retaining the original design structure.
This exercise is part of the course
Analyzing Survey Data in R
Exercise instructions
- Use
subset()
to create a new design object,NHANES20_design
, which only contains the 20-year-olds. - Using
svyglm()
, build a simple linear regression model forWeight
usingHeight
with the design objectNHANES20_design
and store it asmod
. - Print out a summary of the model.

Have a go at this exercise by completing this sample code.
# Subset survey design object to only include 20 year olds
NHANES20_design <- subset(___, Age == ___)
# Build a linear regression model
mod <- svyglm(___ ~ ___, design = ___)
# Print summary of the model
___(___)
