Parametric or non-parametric statistical tools applied to marine aerosol sampling

Atmospheric aerosol sampling has been performed in parallel with both high and low air flows. A comparison of the results requires proper statistical design and analysis. The presence of several outliers and the increase of residuals with increasing concentration have led to the recommendation of handling the data with non-parametric methods rather than parametric statistical analysis.Conversion equations were obtained for each of the ionic species examined for prediction of low air flow sampling from long-term observations with high air flow sampling.
