Glucose and Triglycerides Levels in Blood

Description

Simulated data for glucose and triglycerides levels in blood in 400 adults.

Usage

glucose

Format

A data.frame with 400 observations on the following 4 variables:

trigly

triglycerides levels in blood (mg/dl).

gluco

glucose levels in blood (mg/dl).

inv12tri

numeric. Reciprocal of the square root of trigly (i.e., -1/2 power transformation).

inv2glu

numeric. Reciprocal of the gluco square (i.e., -2 power transformation).

Details

Data were simulated to emulate true data pattern observed in a real study (see References).
