Cardiological Interval Data Set

A real interval-valued data set.

data("Cardiological.CR")

Format

A data frame containing following variables:

PulseMin

Lower bound of the response interval-valued variable Pulse

SystMin

Lower bound of the explanatory interval-valued variable Systolic Pressure

DiastMin

Lower bound of the explanatory interval-valued variable Diastolic Pressure

PulseMax

Upper bound of the response interval-valued variable Pulse

SystMax

Upper bound of the explanatory interval-valued variable Systolic Pressure

DiastMax

Upper bound of the explanatory interval-valued variable Diastolic Pressure

Details

This data set concerns the record of the pulse rate (Y), systolic blood pressure (X1) and diastolic blood pressure (X2) from 11 patients.
