Ozone Air Quality Histogram-Valued Dataset

Description

Histogram-valued dataset of 84 daily observations with 4 weather-related histogram variables. Each histogram has 10 equal-probability (decile) bins summarizing hourly measurements within each day.

Usage

data(ozone.hist)

Format

A data frame with 84 observations (days) and 4 histogram-valued variables:

• Ozone.Conc.ppb: Histogram of ozone concentration (ppb).

• Temperature.C: Histogram of temperature (Celsius).

• Solar.Radiation.WattM2: Histogram of solar radiation (W/m^2).

• Wind.Speed.mSec: Histogram of wind speed (m/s).

Row names are I1 through I84.
