Short summary
This paper presents a new methodology to treat statistically pyroclast density and porosity data sets introducing a weighting parameter. It also proposes a stability analysis to check if the sample set is large enough for statistical reliability. Finally we introduce graphical statistics to improve distinction between pyroclastic deposits and understanding of eruptive dynamics. An open source R code is supplied that includes all these features in order to facilitate data processing.
