%description
Estimates DNA target concentration by classifying digital PCR (polymerase
chain reaction) droplets as positive, negative, or rain, using
Expectation-Maximization Clustering. The fitting is accomplished using the
'EMMIXskew' R package (v. 1.0.3) by Kui Wang, Angus Ng, and Geoff
McLachlan (2018) as based on their paper "Multivariate Skew t Mixture
Models: Applications to Fluorescence-Activated Cell Sorting Data"
<doi:10.1109/DICTA.2009.88>.
