glucose: Glucose and Triglycerides Levels in Blood

In tlm: Effects under Linear, Logistic and Poisson Regression Models with Transformed Variables

Description

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

Usage

data(glucose)

Format

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

trigly

numeric triglycerides levels in blood (mg/dl).

gluco

numeric 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’).
