endosim: Simulated endocrine data.

Description Usage Format Source References Examples


The endosim data set was simulated based on the data analyzed in Rodriguez-Alvarez et al. (2011a,b) and presented in Botana et al. (2007) and Tome et al. (2008). The aim of these studies was to use the Body Mass Index (BMI) to detect patients having a higher risk of cardiovascular problems, ascertaining the possible effect of age and gender on the accuracy of this measure.




A data frame with 2840 observations on the following 4 variables.


patient's gender. Factor with Male and Female levels.


patient's age.


true disease status (presence/absence of two of more cardiovascular risk factors according to the International Diabetes Federation). Numerical vector (0=absence, 1=presence).


patient's body mass index.
