Cardiological Interval Data Set (Centre and Range)

A real interval-valued data set represented in terms of the centre and the range of the intervals.

data("Cardiological.CR")

Format

A data frame containing the following variables:.

PulseC

The midpoint of the response interval-valued variable Pulse

SystC

The midpoint of the explanatory interval-valued variable Systolic Pressure

DiastC

The midpoint of the explanatory interval-valued variable Diastolic Pressure

PulseR

The range of the response interval-valued variable Pulse

SystR

The range of the explanatory interval-valued variable Systolic Pressure

DiastR

The range 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.
