r-cran-eco 4.0-1-1 (s390x binary) in ubuntu bionic

 This is a set of routines for GNU R that implement Imai and Lu's
 parametric and nonparametric Bayesian ecological inference algorithms
 using Markov chain Monte Carlo estimation. Ecological inference is a
 statistical technique designed to recover individual-level information
 from aggregate-level data.
 .
 The suggested r-cran-mcmcpack package includes other EI estimators that
 may be useful alternatives to those included in this package.
