%description
Estimates the probability matrix for the R×C Ecological Inference problem
using the Expectation-Maximization Algorithm with four approximation
methods for the E-Step, and an exact method as well. It also provides a
bootstrap function to estimate the standard deviation of the estimated
probabilities. In addition, it has functions that aggregate rows optimally
to have more reliable estimates in cases of having few data points. For
comparing the probability estimates of two groups, a Wald test routine is
implemented. The library has data from the first round of the Chilean
Presidential Election 2021 and can also generate synthetic election data.
