In MultiSkew: Measures, Tests and Removes Multivariate Skewness

Description

The PM10 dataset provides an evaluation of PM10 (particulate matter with an aerodynamic equivalent diameter of up 10 m ) concentrations recorded in Italy during year 2006. The variables, collected from 257 stations, are: average (MEAN) and 50th percentile (MEDIAN) for stations which have valid data with a time coverage of at least 50; 98th percentile (98TH) and maximum value (MAX). Stations are classified by region, province and zone (rural, urban, suburban).
